<p>A chip-type positive temperature coefficient thermistor element (1) has an element volume of no more than 0.12 [mm3]. In order to improve responsiveness, the following are provided: a ceramic base material (2) which has end surfaces (Sa, Sb) that face one another in parallel in the X axis direction and side surfaces (Sc) that connect the end surfaces (Sa, Sb), and the inner resistance value of which changes according to a temperature change; and a metal-containing first external electrode (4a) and second external electrode (4b) that are provided on the end surfaces (Sa, Sb). The distance (d [μm]) in the X axis direction between the end surfaces (Sa, Sb) is 300≤d≤700, and the maximum point thickness (tmax [μm]) of the thickness in the X axis direction of the first external electrode (4a) and the second external electrode (4b) is tmax≥0.015 x d - 1.5.</p> |
