The first spring 125 provides an elastic force acting on the probe mounting plate 122. The second spring 124 is connected between the tail of the positive and negative pole probes 121 and the probe fixing plate 123. The first spring 125 provides an elastic force acting on the probe fixing plate 123, that is, the external force moves the probe mounting plate 122 and the probe fixing plate 123. The first spring 125 and the second spring 124 are in a compressed state. An object (such as the fixing part 11) is placed between the probe mounting plate 122 and the probe fixing plate 123.
