Chip thermistor

摘要

A chip thermistor includes a thermistor element body and a pair of outer electrodes. The thermistor element body has a pair of end faces opposing each other and a main face connecting the end faces to each other. The pair of outer electrodes are arranged on the pair of end faces, respectively. The pair of outer electrodes have a width in a direction intersecting the opposing direction of the pair of end faces made narrower with distance from the thermistor element body.

1. A chip thermistor comprising:
a thermistor element body having a pair of end faces opposing each other and a main face connecting the end faces to each other; and a pair of outer electrodes arranged respectively on the pair of end faces, wherein each of the pair of outer electrodes is formed into a truncated quadrangular pyramid and has a width in a direction intersecting the opposing direction of the pair of end faces made narrower with distance from the thermistor element body; wherein each of the pair of outer electrodes has a foundation electrode layer arranged on a respective one of the end faces and a plating film covering the foundation electrode layer; and wherein each foundation electrode layer is formed into a truncated quadrangular pyramid and has a width in the direction intersecting the opposing direction not greater than that of the respective one of the end faces and made narrower with distance from the thermistor element body.
