An optical element includes: a glass substrate; an optical function portion made of a resin; and a bonding portion that bonds the glass substrate and the optical function portion to each other. The bonding portion has a glass transition point of 85&#xb0; C. or lower. The glass transition point of the bonding portion may be 50&#xb0; C. or lower.

Optical element, optical system and optical device

A method of producing an optical component includes a transfer step of sandwiching a molding material layer of a molding material between a thin glass plate and a mold and transferring an indented pattern on the mold to the molding material layer to form a patterned indented layer on the thin glass plate, and a separation step of separating the mold from the patterned indented layer. During the transfer step, a reinforcing plate is removably attached to the thin glass plate.

A light guide element includes a light-guiding substrate and a diffraction part formed on a surface of the light-guiding substrate. The diffraction part includes an optical layer capable of exerting a diffractive action. The distance from the light-guiding substrate to a surface of the optical layer is equal to or less than 10% of a thickness of the light-guiding substrate. The light guide element satisfies |&#x394;D|&#x2266;0.15 mm, where &#x394;D is an amount of a change in D with the temperature change &#x394;T, D [mm] is a distance, at the temperature T (&#xb0; C.), between the center of the diffraction part and a position predetermined as a position where the ray of light comes out of the light-guiding substrate in a direction horizontal with respect to the light-guiding substrate, and &#x394;T is a temperature change.
