PROBLEM TO BE SOLVED: To provide a gap confirmation tool, capable of verifying the size of a gap across a pair of members which have surfaces facing each other, at an arbitrary location. SOLUTION: The gap confirmation tool includes both a head part 2 and a rod-like part 3, connected to the head part 2. In the head part 2 in its projected shape projected to a plane intersecting with the direction of extension of the rod-like part 3 at right angles, when the head part 2 is projected to the direction of extension of the rod-like part, the distance between two points farthest in linear terms from each other becomes a specified length, and the overall projected shape is contained within a virtual circle, having a radius equal to half the length of the regular length from the center between the two points.
