Zusammenfassung:An insulating film includes an insulating layer and a surface bonding layer disposed on the insulating layer. The surface bonding layer includes a radical generation element and a coordinate bond element. In the surface bonding layer, a/b is 0.05 or more and 0.35 or less, in which 'a' is an atom content of the coordinate bond element and 'b' is an atom content of the radical generation element.
