A method for surface mounting an electronic component includes providing a conductive circuit on a substrate member, forming a thermoplastic resin layer on a front surface of the conductive circuit, providing a surface of an electrode of an electronic component with a metal layer, and bonding the metal layer of the electronic component and the conductive circuit to each other by melting and partially removing a thermoplastic resin by applying a load generated by ultrasonic vibration that vibrates in a direction substantially parallel to a surface of the metal layer, while pressing the metal layer to the thermoplastic resin layer, and then stopping applying the load generated by the ultrasonic vibration, and hardening the thermoplastic resin thus melted by cooling. The metal layer is configured by a thin layer made of a material having a shear strength lower than that of a material constituting the conductive circuit.
