Claims

[Claims for Utility Model Registration] (1) A semiconductor ceramic having positive or negative resistance-temperature characteristics, in which a plurality of internal electrodes are arranged so as to overlap each other via a ceramic layer, and a semiconductor ceramic having a positive or negative resistance temperature characteristic; A laminated thermistor element body including an external electrode formed for electrical connection, and legs fixedly provided on the thermistor element body and for attaching to a mounting target member. Features a chip-type thermistor. (2) The chip-type thermistor according to claim 1, wherein the leg portion is integrally formed of the same material as the semiconductor ceramic. (3) The chip-type thermistor according to claim 1, wherein the leg portion is constituted by a member separate from the thermistor element body. (4) The leg has a fitting part into which a part of the thermistor element body is fitted, and the thermistor element body is fitted and held in the fitting part, the scope of the utility model registration claim. The chip-type thermistor according to item 1 or 3. (5) The legs include a first leg extending to one side of the thermistor element body and a second leg extending to the opposite side of the thermistor element body, and the first leg or the second leg A chip-type thermistor according to any one of claims 1 to 4, which is capable of being surface-mounted using any of the above. (6) The chip-type thermistor according to claim 1 or 3, wherein the leg portion is made of a metal material and also serves as the external electrode.
