Abstract:
1. An image-capturing apparatus comprising a metal member contact structure comprising: a first metal member having a first corrosion potential; a second metal member having a second corrosion potential; and a third metal member having a third corrosion potential, wherein the second corrosion potential is at a level between the first corrosion potential and the third corrosion potential, the second metal member has a machined surface on one side, and the third metal member contacts the machined surface, the first metal member constitutes a body, the second metal member constitutes a mounting member used to mount the third metal member, and the second metal member is machined to ensure that when the third metal member is placed in contact with the machined surface of the second metal member, an image-forming plane of a photographic lens becomes substantially aligned with a light-receiving surface of an image-capturing element held by the third metal member.
