PROBLEM TO BE SOLVED: To provide a circuit board inspection system which can perform high-reliability electrical inspection, even for a circuit board to be inspected having electrodes with a fine pitch and can perform inspection smoothly, when circuit boards are inspected continuously. SOLUTION: A relay pin unit 31 comprises an intermediate holding plate 36, a first support pin 33 interposed in between a first insulating plate 34 and the intermediate holding plate 36, and a second support pin 37 interposed in between a second insulating plate 35 and the intermediate hold plate 36. A first contact support position 38A of the first support pin, with respect to the intermediate hold plate and a second contact support position 38B of the second support pin, with respect to the intermediate hold plate, are arranged at different positions on an intermediate hold plate projected plane A, which is projected in the direction of the thickness of the intermediate holding plate. By having a conductive pin 32 pressed into the lateral direction by a bending holding plate 84 interposed between the first or second insulating plate and the intermediate hold plate, the conductive pin 32 is supported movably in the axial direction.
