The adhesive film includes an insulating film, an adhesive layer provided over one side of the insulating film, and an anchor coat layer provided between the one side of the insulating film and the adhesive layer. The adhesive layer is a copolymer polyamide resin which is soluble in a solvent at 25 degrees Celsius and has a melting point of 100 degrees Celsius or more and 150 degrees Celsius or less. The anchor coat layer enhances the adhesion between the insulating film and the adhesive layer.
