Electrical connection of a measuring socket to an IC package, to measure electrical characteristics of the IC package, is realized by bringing a measuring pin of a measuring arm of the measuring socket into contact with an end surface of a distal end of a lead of the IC package. Accordingly, a problem of solder plated to the lead becoming attached to and deposited on an upper side of a socket pin and shaved off by the distal end of the lead, and thereby producing solder residue, is solved. This problem occurs when electrical connection to an IC package is conventionally realized by bringing the distal end of the lead of the IC package into contact with a distal end of the socket pin.
