(57) [Problem] To perform buckling deformation even when a conductive fiber is compressed when conducting an electrical inspection of an electric circuit component using a fiber-oriented anisotropic conductive sheet. The electrical contact between the electrode to be inspected of the electric circuit component and the connection electrode of the circuit board for inspection is reliably ensured and can be used repeatedly, and the surface of the portion of the electric circuit component other than the electrode to be inspected. To prevent damage. SOLUTION: The conductive fiber has a conductive fiber oriented in a thickness direction, A fiber-oriented anisotropic conductive sheet provided with a protruding electrode portion at a predetermined site, between a pair of pole plates, a conductive sheet material containing conductive fibers, and between the conductive sheet material and the pole plate. Placing the resist material, heating while applying a magnetic field to the pole plate, orienting the conductive fibers, controlling the distance between the two pole plates, projecting the conductive fibers in the resist layer, By selectively removing the resist layer, the remaining portion was used as a protruding electrode portion. |
