Abstract:
1. A sheet-like probe comprising: an insulating layer; and a contact film including a plurality of electrode structures disposed on the insulating layer apart from each other by 40 to 160 μm in a planar direction thereof and extended to penetrate in a direction of a thickness of the insulating layer, at least part of the electrode structures including a metal extended to penetrate in the direction of the thickness of the insulating layer through a tapered through hole of the insulating layer to fill in the tapered through hole by carrying out a plate treatment, the tapered through hole being formed in the insulating layer by an etching treatment, each of the electrode structures including: wherein a diameter of the base end of the surface electrode portion is larger than a diameter of the end of the side which comes into contact with the surface electrode portion on the short circuit portion, and a thickness of the short circuit portion is larger than a thickness of the insulating layer.
