PROBLEM TO BE SOLVED: To provide a finder device capable of simplifying and miniaturizing the structure of a finder by a method, in which a prism is provided inside the finder and a necessary optical path is secured by utilizing reflection inside the prism. SOLUTION: By providing a pentaprism 32 inside a finder 30, light is reflected inside and a prescribed optical axis length can be secured. Then, a processing in which a video is reflected is performed to 1st and the 2nd surfaces 32a and 32b of the prism 32 by vapor-depositing processing, whereby the increase in the number of parts items is restrained.
