SOLUTION: An optical scanner includes deflection means 45 for deflecting light and a housing including a casing 50 in which the deflection means 45 is stored and a cover 57 attached to the casing 50 and covering the inside of the casing 50. The housing includes a through-hole 59 through which the inside and outside of the housing are communicated with each other and an attachment part 58 to which an elastic member 53 covering the through-hole 59 in such a state that the cover 57 is attached to the casing 50 can be attached. The housing includes a regulation part 54 covering a part of the elastic member 53 attached to the attachment part 58, when viewed from the attachment direction of the elastic member 53 and regulating the movement of the elastic member 53 in a direction opposite to the attachment direction from the atta
