PROBLEM TO BE SOLVED: To provide a multilayered composite ceramic made of a PTC (a semiconductor exhibiting a positive temperature characteristic of resistance) ceramic device, an NTC ceramic device or a fixed resistance ceramic device, and an electrode which are integrated and a multilayered composite ceramic device. SOLUTION: A multilayered composite ceramic device 2 consists of a multilayered ceramic body made of a PTC ceramic device 2 and an NTC ceramic device or a fixed resistance ceramic device 1 which are integrated. The PTC ceramic device 2 consists of a PTC ceramic whose major constituent is barium titanate. The NTC ceramic device or the fixed resistance ceramic device 1 consists of an NTC-R ceramic whose major constituent is barium titanate. A multilayered composite ceramic device 4 provided with an inner electrode 3 in a multilayered ceramic body made of at least the PTC ceramic device 2 and the NTC ceramic device or the fixed resistance ceramic device 1 which are integrated. |
