Abstract:
1. A sheet-like probe comprising: a contact film including an insulating layer, and a plurality of electrode structures disposed on the insulating layer apart from each other in a planar direction thereof and extended to penetrate in a direction of a thickness of the insulating layer; and a perforated film, wherein the contact film is supported to penetrate in each position of a plurality of through holes formed in the perforated film, the perforated film and a peripheral edge portion of the contact film are integrated with each other in such a manner that the insulating layer made of a flexible resin is included in a fine hole of the perforated film, and wherein each of the electrode structures include: a surface electrode portion exposed from a surface of the insulating layer and projected from the surface of the insulating layer, a back electrode portion exposed from a back face of the insulating layer, a short circuit portion extended to penetrate through the insulating layer in a direction of a thickness thereof continuously from a base end portion of the surface electrode portion and coupled to the back electrode portion, and a holding portion extended outward along the surface of the insulating layer continuously from the base end portion of the surface electrode portion, and wherein the perforated film is provided with a ring-shaped support plate bonded and fixed to a peripheral edge portion thereof, and the perforated film and the ring-shaped support plate are bonded and fixed by an adhesive impregnated into the perforated film in a contact state thereof with each other.
