PROBLEM TO BE SOLVED: To provide a technology for highly sensitively detecting an overcurrent in a micoscopic spatial position for highly sensitively detecting and evaluating an occurrence of an electrostatic amount, in a step for manufacturing an electronic device, especially in the step of manufacturing a magnetic disc head element or the like. SOLUTION: The overcurrent detecting element comprising electrode pads on both ends; an electric wiring part for connecting the electrode pads; and a temperature sensitive pellet on the surface of the electric wiring on a board having at least insulating surface measures an appearance shape of the temperature-sensitive pellet, after the current passes through the electric wiring to detect an amount of the current passing through the electric wiring part on the basis of a change in shape of the temperature-sensitive pellet.
