An imaging device to which a support can be attached includes a support attachment unit and a support body unit. The support attachment unit includes a first threaded hole configured to be attached to the support, and an exposure face formed around the entrance of the first threaded hole. The support body unit includes a housing having an opening configured to expose the exposure face and an outer surface formed around the opening, and movably supports the support attachment unit. The support attachment unit is disposed at a first position when the support is not attached, and is disposed at a second position when the support is attached. The exposure face is disposed more to the inside of the housing than the outer surface when the support attachment unit is disposed at the first position.
