Patent ID: 8096840

Claim:
A conductive contact holder that supports a plurality of conductive contacts for electrically connecting different circuit structures to input and output signals, the conductive contact holder comprising: a holder substrate capable of individually receiving the conductive contacts; and a floating member attached to the holder substrate such that a distance from a surface of the holder substrate is varied within a predetermined range by an external force, the floating member having a plurality of hole sections into which a front end section of each of the conductive contacts received by the holder substrate is inserted, wherein a gap between the holder substrate and the floating member forms at least a part of a passage of fluid introduced from outside of the conductive contact holder; and, wherein the holder substrate includes first and second substrates that are tabular-shaped and stacked in a direction of plate thickness, and a gap formed between the stacked first and second substrates forms at least a part of the passage of fluid introduced from the outside of the conductive contact holder.
