Abstract
A thermistor which includes a ceramic sintered body formed of a plurality of inner electrodes alternating with a corresponding plurality of ceramic layers, outer electrodes being connected to specific ones of the inner electrodes. Each ceramic layer a positive temperature coefficient of resistance. The inner electrode layers are obtained by injecting molten base metal having a low melting point such as lead, tin or lead-tin alloy into gap layers previously defined in the sintered body between the laminated ceramic layers from the outside under pressure and hardening the same.
