An attachment (4) comprises an attached portion (42) that is attachable to, and detachable from, the outer circumferential surface of a game controller (2) and a grip (41) to be held by a user. The attached portion (42) is formed such that the front end (42e) thereof is positioned further rearward than the light emitting part (21) when the attached portion (42) is attached to the game controller (20). According to the attachment (4), it is possible to prevent deterioration in recognition of the light emitting part by the image capturing unit. |
