ABSTRACT:
The present invention relates to a camera with the main circuit boards and the sub-circuit boards comprising electrical circuit constructions having resistance-conductor laminated constructions so designed that the insulating support on which a resistance material layer and a conductor material layer are laminated are processed by means of selective etching. This is done in such a manner that the resistance members are constituted with the resistance material layer while the conductor parts such as wiring, terminals and so on are constituted with the conductor material layer.
