A planar antenna has a circuit pattern including an antenna part and a connection terminal part on a plastic film, in which the circuit pattern has a metal layer and a heat-sealable conductive layer provided on a surface layer of a connection terminal part of the metal layer. The planar antenna is obtained by forming a circuit pattern including a metal layer on a plastic film, providing a heat-sealable conductive layer in a connection terminal part of the circuit pattern, and then removing an unnecessary part with etching.
