1. A pattern fuse comprising:
a first electroconductive line portion having a predetermined length configured to block current to inhibit breakage of functional elements;
a first film layer;
at least one opening formed in the first film layer,
wherein the first electroconductive line portion is located in the at least one opening;
a flame retardant coating layer formed on a first surface of the first film layer;
an adhesive layer formed on a second surface of the first film layer, the first electroconductive line portion being formed on the adhesive layer abutting the second surface; and
a second film layer formed on a surface of the adhesive layer opposite a surface of the adhesive layer on which the first electroconductive line portion is formed,
wherein adhesion between the first electroconductive line portion and the adhesive layer is greater than adhesion between the first electroconductive line portion and the coating layer,
wherein a melting point of the coating layer is higher than a melting portion of the first film layer, and a thermal conductivity of the coating layer is lower than a thermal conductivity of the first film layer, and
wherein the thermal conductivity of the coating layer is 0.10 W/mk or less.
