A sensor including a light-receiving element; and an optical element that includes near infrared absorbing dichroic substance. The optical element has an absorption axis with respect to near infrared light in an in-plane direction. When linearly polarized light of near infrared light orthogonal to the absorption axis is radiated from a normal direction of the optical element and from a direction inclined by 45° from the normal direction at an azimuthal angle orthogonal to the absorption axis, an absorbance during the radiation from the direction inclined by 45° from the normal direction is more than an absorbance during the radiation from the normal direction.

In Expressions (1) and (2) Re(450) represents an in-plane retardation of the optically anisotropic film at a wavelength of 450 nm, and Re(550) represents the in-plane retardation of the optically anisotropic film at a wavelength of 550 nm.
