Abstract
An optical scanner contains in a casing made of thermoplastic material a light source that emits an image light based on image data, and at least one optical element that is disposed in an optical path for the image light. The optical element is held through a holding member by the casing. The holding member is uprightly held at one edge portion thereof on an inside surface of the casing, and secures the optical element at the other edge portion thereof. The holding member has a shape that causes a thermal deformation in which a leaning direction of the other edge portion is opposite to a leaning direction of the one edge portion due to a thermal deformation of the inside surface of the casing when a temperature of the casing rises.
