PROBLEM TO BE SOLVED: To inspect a printed circuit board wherein electronic parts covered with flux are mounted by contacting a probe to the printed circuit board. SOLUTION: A probe is heated from the root of a probe substrate wherein the probe is erected, by means of a cable from a heating substrate 60. The temperature of the probe is measured by a temperature detector attached to the probe, and the heater 65 of the heating substrate 60 is controlled. The probe is pressed down to the pad of a mounting printed circuit board as a reference wherein parts are mounted, and the flux of the printed circuit board is softened by the heated probe and connected with solder on the pad, thereby measuring a resistance value.
