An electronic still camera has a photographing system, a photographing element 15a located at a surface of the photographing optical system on which an image is formed and a finder optical unit 20 disposed separately from the photographing optical system 11. An optical path of the finder optical unit comprises a forward optical path disposed in parallel to and close to the photographing optical system, a rearward optical path disposed at a position away from an optical axis of the photographing optical system farther than the forward optical path and a refracted optical path for connecting the forward optical path to the rearward optical path disposed at a position forward of the photographing element. <IMAGE>
