Abstract
Provided is a sensor element capable of obtaining a wide sensing region, suppressing unevenness of a temperature distribution in the sensing region, and obtaining substantially constant sensor sensitivity. A sensor element according to the present invention includes: a base; a temperature-sensitive film formed on an entire surface of the base and having an electric resistance value that changes due to a change in temperature; and wiring members connected to both ends of the temperature-sensitive film. The temperature-sensitive film includes connection regions connected to the wiring members and a pattern extending from each of the connection regions toward a center of the base, and a cross-sectional area of the pattern is smaller on the connection region sides than at the center of the base.
