A heat-transfer member () is used in a cooling system in which an alcohol serves as a coolant. The heat-transfer member () has: a heat-receiving surface () configured such that it can receive heat from a heat-generating body; and a heat-dissipating surface () configured such that it can dissipate, to the coolant, the heat received at the heat-receiving surface (). The heat-dissipating surface () has a plurality of pores () whose average pore diameter is 5 nm or more and 1,000 nm or less. A cooling system can be configured by causing the coolant to contact the heat-dissipating surface () of the heat-transfer member ().

An IC device to be inspected is received in a chamber, and an IC tester Judges performance of the IC device. An electrical connection device is arranged outside the chamber and has a conductive passage electrically connecting between the IC tester and the IC device. An IC socket is retained on the electrical connection device, for having the IC device inserted therein. A magnetometric sensor is arranged close to the conductive passage of the electrical connection device, for detecting a magnetic field generated when electric current is supplied to the IC device. A temperature control device controls a temperature of the IC device. A control unit controls the temperature control device based on a signal delivered from the magnetometric sensor, to maintain the temperature of the IC device within a predetermined temperature range.
