An in-finder indicator for a single-lens reflex camera, comprising: an eyepiece lens; a reflecting mirror for reflecting a beam of light from a subject; a screen having a screen surface which is subjected to surface treatment to form prisms for presenting a superimposed indication and which forms an image of the subject based on the light beam reflected by the reflecting mirror; a dach mirror having a pair of mirror surfaces for reflecting the light beam from the screen and being open along opposite lateral sides of the dach mirror; a reflecting surface for reflecting the light beam reflected by the mirror surfaces of the dach mirror and introducing the light beam to the eyepiece lens; and an illumination member disposed at a space in a direction lateral to a region between the mirror surfaces of the dach mirror and the screen for introducing an illumination beam to enter the screen surface from a direction lateral to a direction of the image formed on the screen surface.
