A multilayer positive temperature coefficient thermistor that has semiconductor ceramic layers containing a BaTiO3-based ceramic material as a primary component, and at least one element selected from the group consisting of Eu, Gd, Tb, Dy, Y, Ho, Er, and Tm as a semiconductor dopant in the range of 0.1 to 0.5 molar parts with respect to 100 molar parts of Ti. The ratio of the Ba site to the Ti site is in the range of 0.998 to 1.006. Accordingly, even when the semiconductor ceramic layers have a low actual-measured sintered density in the range of 65% to 90% of a theoretical sintered density, a multilayer positive temperature coefficient thermistor having a sufficiently high rate of resistance change and a high rising coefficient of resistance at the Curie temperature or more can be realized.
