The invention relates to an optical element. The optical element includes an optically effective surface and an optically non-effective surface, and a light-shielding coating film is formed on the optically non-effective surface. The optically non-effective surface includes a round-chamfered concave step corner section, the light-shielding coating film is formed over the entire concave step cornersection, the light-shielding coating film has a raised area near a location where one of planes of the concave step corner section is connected to the round chamfer. Consequently, film cracking of the optically non-effective surface of a stepped shape is inhibited and a reliable optical element is provided. The invention also relates to an optical device and a method of producing the optical device.
