Abstract
An optical phase shifting plate includes: an optical substrate configured to change a refractive index for light which passes through the optical substrate by a thermooptical effect; a thin-film heater formed on a surface of the optical substrate; a wiring member disposed to be substantially perpendicular to the surface of the optical substrate; an intermediate member disposed between the optical substrate and the wiring member, the intermediate member having: a first surface that is substantially flush with a surface of the thin-film heater; and a second surface that is substantially flush with a surface of the wiring member and that is perpendicularly adjacent to the first surface, a first bonding wire which electrically connects the surface of the thin-film heater to the first surface of the intermediate member; and a second bonding wire which electrically connects the surface of wiring member to the second surface of the intermediate member.
