ABSTRACT:
An electrical connecting device is disposed between a circuit board and a probe board opposing each other and used for connection between electrical connection terminals provided on the underside of said circuit board and electrical connection terminals provided on the probe board. In the electrical connecting device, an electrical insulating board has at least one of conductive earth patterns to be maintained at the earth potential on at least one selected from groups including the upside, underside and inside of the electrical insulating plate; a connecting pin disposed in each through hole of a first group is connected to the earth pattern, while a connecting pin disposed in each through hole of a second group is electrically separated from the earth pattern.
