PROBLEM TO BE SOLVED: To provide an inspection tool capable of preventing swing of a plunger with a simple structure, and inspecting highly accurately a highly-densified wiring circuit. SOLUTION: The plunger 3 held movably forward and backward is provided on a tool base 2. The plunger 3 is equipped with a connection part 8 for eccentrically connecting an elongation part 7 elongating to the outward of the tool base 2 to a base part 6. The tool base 2 is equipped with a pair of plate members 13a, 13b for holding the connection part 8, and both plate members 13a, 13b are equipped with a guide part 19 for guiding the connection part 8. The guide part 19 comprises approximately complete round holes 19a, 19b in the same shape formed on both plate members 13a, 13b. A part of the fringe of both holes 19a, 19b abuts on the connection part 8 from the direction straight to the eccentric direction. COPYRIGHT: (C)2006,JPO&NCIPI
