ABSTRACT:
There is provided an optical apparatus which has excellent assembly performance, can suppress an increase in cost, and attain a decrease in thickness. The optical apparatus includes a board (1) having a photographing optical system and a mechanical system mounted on its surface. A plurality of opening portions (1a, 1b, 1c) are formed in the board (1). The opening portion (1a) is sealed with a sealing member such as a glass member to allow a light beam to pass and prevent dust and the like from entering the storage space for parts between the board (1) and a shield case (49). The photographing optical system mounted on the board (1) includes a stop unit (30) for adjusting the light amount of an object image guided through the opening portion (1a), and prism-like optical members (G1, G2, G3, G4), each consisting of, e.g., a glass or plastic material and having a sculptured surface as a reflecting surface. Light emerging from the optical member (G4) is received by a solid-state image sensing element (2) mounted on the lower surface of the board (1) through the opening portion (1c).
