Abstract

The present invention discloses an over-current protection apparatus, comprising a current-sensitive element, a first electrode and a second electrode. The over-current protection apparatus of the present invention is a three-dimensional multi-layer structure, and can be formed by heating, pressing, etching, cutting and multi-stage deformation to prevent it from breakage during the bending process. Therefore, the over-current protection apparatus with at least one bend is formed.
