Abstract
A semiconductor ceramic composition for use as a component of the body of NTC thermistors contains at least manganese and cobalt as main ingredients and both aluminum and titanium as additional ingredients for resistance adjustment by annealing. It becomes easier to adjust the resistance of the composition by annealing when the titanium content is equal to or lower than about 9.2 parts by weight on a TiObasis relative to 100 parts by weight of the main ingredients.
