Abstract: A fingerprint recognition sensor having an excellent S/N ratio and capable of realizing thinning and an optical element including the fingerprint recognition sensor. The fingerprint recognition sensor includes a light-receiving element; and an optical element including a near infrared absorbing dichroic substance, in which a fingerprint reading surface is positioned on a side of the optical element opposite to the light-receiving element side. 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.
