An inclined surface-equipped lens includes a first inclined surface and a second inclined surface inclined relative to a plane perpendicular to an optical axis, and a corner portion formed by the first inclined surface and the second inclined surface being in contact with each other. Each inclined surface makes a predetermined inclination angle with the plane perpendicular to the optical axis, and the corner portion is located out of the optical axis and raised outward.
