Provided is a protection element wherein a flux on a soluble conductor can be stably held at a predetermined position, the status wherein the flux is being held can be confirmed, and the soluble conductor can speedily fuse when abnormality occurs. The protection element has: a soluble conductor (13), which is arranged on an insulating base substrate (11), is connected to the power supply line of an apparatus to be protected and fuses with a predetermined abnormal power; a flux (19) applied on the surface of the soluble conductor (13); and an insulating cover (14) which covers the soluble conductor (13) and is attached to the base substrate (11). The insulating cover (14) is provided with an opening section (20) composed of a through hole facing the soluble conductor (13). The flux (19) is brought into contact with the periphery of the opening section (20) and holds the flux (19) at the predetermined position on the soluble conductor (13). |
