An endoscope apparatus includes two optical path forming optical systems, an image forming optical system, two convex power sections including a convex section, provided in the two optical path forming optical systems, and disposed so as to emit emitted light from the two optical path forming optical systems to the image forming optical system, and an aperture member including two openings configured to transmit the light emitted from the two convex power sections. The centers of the two openings are respectively located on the optical axis side of the image forming optical system with respect to the two optical axes of the two optical path forming optical systems.
