(57) [Summary] [Purpose] When Ni-based metal is used for the internal electrodes, low-temperature reoxidation treatment can be performed without damaging ohmic contact, which in turn can reduce the specific resistance and improve the temperature coefficient of resistance. A laminated semiconductor porcelain composition capable of being provided. [Structure] In the case of forming a laminated semiconductor ceramic 1 having a positive resistance temperature characteristic, which is formed by alternately laminating semiconductor ceramic layers 2 and internal electrodes 3, a sintered body 4 is formed. The molar ratio Ba site / Ti site is set to 0.99 to 1.05, a part of the Ba site is converted to Ca and is replaced with Ca in the range of 5 to 40 mol%, and manganese is converted to Mn to 0.005 to 1 mol. Add in the range of%. |
