PROBLEM TO BE SOLVED: To provide an imaging device that is excellent in dust-proofness and assemblability of a finder unit by improving accuracy of positioning an elastic dust-proof member and penta dach prism.SOLUTION: In an imaging device comprising a finder unit including: a penta dach prism; a penta holder for holding the penta dach prism in a camera main body; and an elastic dust-proof member to be bonded between the penta dach prism and the penta holder, a plurality of the elastic dust-proof members is bonded to an entire periphery of a penta dach prism side face, and at least one elastic dust-proof member is composed of three of a dust-proof member, adhesion member, and positioning member. In at least one elastic dust-proof member, when a:a dust-proof member outer shape, b:an adhesion member outer shape, and c:a positioning member shape, the elastic dust proof member satisfies a<b<c, and the dust-proof member and positioning member are bonded to the same face with respect to the adhesion member, and further the elastic dust-proof member is configured so that the elastic member bonded to opposing each face of a penta dach prism side face is mutually different in repulsive force.SELECTED DRAWING: Figure 7 |
