A surface-mountable negative-characteristic ceramic thermistor (1) based on a ceramic compound composed of a semiconductor ceramic material containing Mn, Ni, Co, and Ti. External electrodes are disposed on surfaces of the ceramic body and plating films are disposed on the external electrodes. The semiconductor ceramic material is composed of Mangan (Mn), nickel (Ni), Cobalt (Co), and Titan (Ti), - the content of (Mn) is in the range of 0.1 mol% to 90 mol%, - the content of (Ni) is in the range of 0.1 mol% to 45 mol%, and - the content of Cobalt (Co) is in the range of 0.1 mol% to 90 mol%, provided that the sum of Mn, Ni, and Co is 100 mol%. When the total molar quantity of Mn, Ni and Co in the semiconductor ceramic material is defined as being 100 parts by mole, -the added content of Ti is in the range of 0.5 parts by mole to 30 parts by mole.
