A sensor device according to the present invention includes a substrate including a heat generation portion, a casing including an accommodation portion accommodating the substrate, and a sensor element including a temperature-sensitive resistor and being supported by the substrate, in which the accommodation portion is divided into a plurality of accommodation spaces on a side closer to the sensor element. The accommodation portion is divided into a first accommodation space and a second accommodation space via division plates, and the first accommodation space is formed on a side closer to the sensor element than the second accommodation space, and widely as compared with the second accommodation space.

Sensor device

A sensor device according to the present invention includes: a sensor element including a temperature-sensitive resistor; and a protective cover that protects the sensor element, wherein the sensor element has a shape extending long along one direction, and the protective cover surrounds a periphery of the sensor element with a plurality of support pillars extending obliquely with respect to a longitudinal direction of the sensor element. It is preferable that the plurality of support pillars intersect in a lattice-like manner.
