Kyocera Corporation (京セラ株式会社, Kyōsera Kabushiki-gaisha, pronounced [kʲoːseɾa]) is a Japanese multinational ceramics and electronics manufacturer headquartered in Kyoto, Japan.

It was founded as Kyoto Ceramic Company, Limited (京都セラミック株式会社, Kyōto Seramikku Kabushiki-gaisha) in 1959 by Kazuo Inamori and renamed in 1982.

It manufactures industrial ceramics, solar power generating systems, telecommunications equipment, office document imaging equipment, electronic components, semiconductor packages, cutting tools, and components for medical and dental implant systems.

The company quickly adapted its technologies to produce an expanding range of ceramic components for electronic and structural applications.

In the mid-1970s, Kyocera began expanding its material technologies to produce a diverse range of applied ceramic products, including solar photovoltaic modules; biocompatible tooth- and joint-replacement systems; industrial cutting tools; consumer ceramics, such as ceramic-bladed kitchen knives and ceramic-tipped ballpoint pens; and lab-grown gemstones, including rubies, emeralds, sapphires, opals, alexandrites and padparadschahs.

Shortly afterward, Kyocera introduced one of the first portable, battery-powered laptop computers, sold in the U.S. as the Tandy Model 100, which featured an LCD screen and telephone-modem data transfer capability.

In the 1980s, Kyocera marketed audio components, such as CD players, receivers, turntables, and cassette decks.

On August 4, 1999, Kyocera completed its merger with solar energy systems integrator Golden Genesis Company (Nasdaq:GGGO).

In April 2009, Kyocera unveiled its EOS concept phone at CTIA, with an OLED and which is powered by kinetic energy from the user.

The merged enterprise continued under the name Kyocera Communications, Inc. Later that month, Kyocera agreed to acquire part of the thin film transistor (TFT) liquid crystal display (LCD) design and manufacturing business of Sony Corporation's subsidiary Sony Mobile Display Corporation.

Kyocera makes phones for some Japanese wireless carriers including au, willcom, SoftBank and Y!mobile.

A 1,900-panel photovoltaic power system is on the roof and south wall of the building, which can supply 12.5% of the facility's needed energy, generating 182 megawatt hours per year.

[20] Between 1978 and 1998, Kyocera and the International Affairs Board of the City of San Diego sponsored an all-expense paid tour of Japan for students from the United States called HORIZON (stylized in all capital letters and designated by year: e.g.

of the J-League (its hometown team; here the word "Kyocera" is written in Japanese katakana, everywhere else in the Latinized logo).
