PROBLEM TO BE SOLVED: To enable inspection of a high-density printed circuit board by a different inspection device by increasing a permissible range of an installation slant angle of each long pin 10 in an inspection jig for the high-density printed circuit board having an inspection head implanted with a large number of the long pins 10 whose tips project from a head plate 12. SOLUTION: In this jig, an upper plate 16 installed with the head plate 12 has a lower plate 18 installed by use of plural elastic ring bodies 17 along the periphery. Plural pin retention plates are installed within an interval between the upper plate 16 and the lower plate 18 in a laminate state. The pin retention plates comprise the pin retention plates installed to the upper plate 16 by posts 25 and the pin retention plates installed to lower plate 18 by posts 26.
