PROBLEM TO BE SOLVED: To enable a user to visually confirm display within a finder without moving the position of an eye by providing a display part with a micro prism and making the incident angle of illuminating light on the micro prism nearly orthogonal to the ridge line of the micro prism. SOLUTION: A reflector 12 is equipped with plural prism aggregate parts 12a to 12e consisting of many fine prisms (micro prism) on its surface (surface on an opposite side to a side opposed to a pentagonal prism) opposed to a focusing screen. A plurality of prism aggregate parts 12a to 12e form focus detection frame 12a to 12e (display part), respectively. They are arranged so that the slopes (ridge lines) of the respective prisms may be nearly orthogonal to the incident light from an LED 15. Thus, LED reflected light from the LEDs 15b to 15e corresponding to the frames 12b to 12e other than the frame 12a of a center area reaches an eyepoint.
