Abstract
A viewfinder unit includes an optical member between a display and an eyepiece, a first member holding the optical member in a direction orthogonal to an optical axis of the optical member, an illuminator, a second member holding the illuminator, a sensor picking up a photographer's eye image, a detector detecting proximity of the eye to the eyepiece, and an opening wider than a display area of the display in the optical axis direction. When the eyepiece is viewed in the optical axis direction, the illuminator is inside the opening and outside the display area. Part of a first area of the optical member, projecting from an outline of the first member in the optical axis direction, is inside the opening in the orthogonal direction, and at least one of the illuminator and the second member is in a second area surrounded by the outline and the first area.
