PROBLEM TO BE SOLVED: To provide an electric inspection board wherein a poor contact caused between a contact pin and the electric inspection board can be prevented when the contact pin, which can move forward/backward, comes into contact with the electric inspection board for electric conduction, to carry out electric inspection of an electric part. SOLUTION: Relating to recessedly forming an electrode pad part P, for recessedly providing the cross sections to an arc shape, first, a die arranged in a pattern of the electrode pad part is formed, which is pressed to a printed wiring board A which is softened under heat for natural pooling, thus a plurality of recess pins whose tip end is worked into semi-spherical form provided. the electrode pad part P is recessed in arc in cross-section so that a contact area S1 between the tip of the contact pin C and the electrode pad part P is larger compared to a flat electrode pad part. Thus, the electric inspection board is surely conductive to the contact pin C, reducing a poor contact.
