1. A test unit that performs testing of two contact targets, at least of one of which includes electrodes on both sides thereof, the two contact targets being substantially plate shaped and arranged in a layering direction thereof, the test unit comprising:
a first contact probe that comes into contact, at one longitudinal direction end portion side thereof, with an electrode provided on a front surface of one of the contact targets, and comes into contact, at the other end portion side thereof, with an electrode of the other contact target; a second contact probe that comes into contact, at one longitudinal direction end portion side thereof, with an electrode provided on a back surface of the one of the contact targets, and comes into contact, at the other end portion side thereof, with an electrode of a substrate that outputs a signal for the testing; a first probe holder including a suction holder that sucks and holds the one of the contact targets and accommodating and holding therein a plurality of the first contact probes according to a predetermined pattern; a second probe holder accommodating and holding therein a plurality of the second contact probes according to a predetermined pattern; and a base portion that is layered over the first probe holder and holds, at a side thereof layered over the first probe holder, the other contact target, wherein a gap is formed between the other contact target and the first probe holder. |
