過表示装置。A current detection part arranged to surround the electric wire, and a shape memory that is always formed in a standby shape and that changes to the originally memorized shape when a predetermined amount of heat is applied to it by detecting an overcurrent in the same detection part and drives the display. A display device that is driven by the display drive of the shape memory member to display an overcurrent passing display, and a return means that returns to the standby shape when the shape memory member is cooled. Current passing indicator.
