Abstract: An inspection jig includes a rod-shaped probe, a first support portion that supports one end portion side of the probe, a second support portion that supports the other end portion side of the probe, and a separation holding member that holds the first support portion and the second support portion to be separated from each other. The first support portion includes a support plate in which a through hole through which the probe is inserted is formed. A reinforcing plate having bending strength stronger than that of the support plate is disposed on a surface of the support plate facing the second support portion.

Abstract: This inspection jig is provided with: an inspection-side support member having a counter plate (51) provided with a facing surface (F) disposed to face the substrate; and an electrode-side support member (6) having supporting plates (61-63) disposed to face an electrode plate (9) located on the side opposite to the facing surface (F) of the counter plate (51) A probe supporting hole (23), into and by which the rear end portion of the probe (Pr) is inserted and supported, is provided in the supporting plates (61-63), and the probe supporting hole (23) is provided with a restricting surface which is formed along a supporting line (V) inclined at a certain angle (θ) with respect to a reference line (Z), and which restricts the rear end portion of the probe (Pr) from moving in the direction perpendicular to the inclined direction of the supporting line (V).

Abstract: A probe has a substantially bar shape, and includes a tip end, a base end, and a body portion that is located between the tip end and the base end and has a thickness in a thickness direction orthogonal to an axial direction of the substantially bar shape thinner than the tip end. The body portion includes a slope surface that is continuous with the tip end and is inclined with respect to the axial direction in a direction in which the thickness becomes gradually thinner with increasing distance from the tip end. A first region having a surface shape that bulges outward is provided in at least a part of the slope surface.
