Patent ID: 7950927

Claim:
A conductive contact holder that holds a circuit structure to be inspected and a conductive contact for inputting and outputting a signal to and from a circuit board or supplying power to the circuit board, the circuit board generating a signal to be supplied to the circuit structure, the conductive contact holder comprising: a first substrate that includes a plurality of openings each holding the conductive contact; a first holding member that is formed by filling the openings with an insulating material that forms a coat covering part or all of a surface of the first substrate and smoothing a surface of the insulating material except part of the coat, and that includes a plurality of holes located at positions corresponding to the openings, respectively, the conductive contact being inserted through each of the holes; a second substrate that is conductive and is substantially identical in shape with the first substrate, the second substrate being layered on the first substrate; and a second holding member that is substantially identical in shape with the first holding member, and includes a plurality of holes each communicating with one of the holes of the first holding member, wherein the coat of the first holding member and a coat of the second holding member are located on opposite surfaces with the first substrate and the second substrate therebetween.
