A pinching tool includes a pair of less deformable elongated plate shape bodies and a resilient body. Each of plate shape bodies has a pinching portion at one end with a flat pinching surface on its inner surface, a supporting portion at another end with a flat contact surface on its inner surface, and a handling portion between the both ends with an inner surface. When the pinching surface and the contact surface of one of the plate shape bodies is brought into contact with those of another of the plate shape bodies, the pinching surfaces and the contact surfaces are respectively tightly in contact with each other. The resilient body is fitted to the supporting portions and couples the pair of the plate shape bodies together to be spring-loaded in a direction of separation of the two plate shape bodies.
