Abstract
Provided are: a sensor that is used as a distance-measuring sensor or the like and where a high SN ratio can be obtained and high-accuracy measurement can be performed even in a case where an environmental temperature changes; and a band pass filter that is used for the sensor. The sensor includes: a light source; a band pass filter; and a light-receiving element, in which the band pass filter includes a band pass layer and a support that supports the band pass layer, and in a case where a thermal expansion coefficient of the band pass layer is represented by α1, an elastic modulus of the band pass layer is represented by E1, a thermal expansion coefficient of the support is represented by α2, and an elastic modulus of the support is represented by E2, α1>α2 and E1<E2 are satisfied.
