摘要： An imaging device is configured to include a finder and an eyecup unit. An eyecup is provided so as to surround an eyepiece window formed on a cover member. A base member holds the eyecup and the cover member. The eyecup is configured to include a curved and hollow eyepiece region, a first holding region comprising a first hole group, and a second holding region comprising a second hole group. The base member is configured to include a first protrusion group corresponding to the first hole group and a second protrusion group corresponding to the second hole group. The first hole group fits with the first projection group, and the second hole group fits with the second projection group.
