Abstract

A temperature sensor in a rotating electric machine is disposed or installed on a surface of a temperature detection object. The temperature detection object, i.e., an installation portion, has a thickness. The temperature sensor has an inner case housing a detector element. The inner case is made of resin. The inner case has a thickness. A temperature detecting device has an outer case housing the temperature sensor. The outer case is made of resin. A linear expansion coefficient of the outer case is, within a certain temperature range including a threshold temperature for a protection of the rotating electric machine, is smaller than an average of linear expansion coefficients of the installation portion and the inner case.
