<p>PROBLEM TO BE SOLVED: To provide a power supply tool capable of accurately executing a conduction test even under a high temperature testing environment.SOLUTION: A tool main body is disposed with three or more positioning projection parts 20 at a position apart in a radial direction from a center CT1 of an arrangement region A. Electrical components are disposed with three or more positioning fitted parts 21 at a position apart in a radial direction from the center CT1. Fitting together with each positioning projection part 20 and each positioning fitted part 21 allows a positioning of the tool main body to be executed for the electrical components. The predetermined absorption gaps S are provided between each positioning projection part 20 and each positioning fitted part 21. Thereby, the positioning projection part 20 allows the positioning fitted part 21 to move in the radial direction due to the difference of a linear expansion coefficient between the electrical components and the tool main body. In addition, the positioning projection part 20 regulates the movement of the positioning fitted part 21 to the direction orthogonal to the radial direction by cooperation of the fitted part between the positioning projection part 20 and the positioning fitted part 21.</p> |
