Abstract:
A contact includes a solder bonding portion, an elastic contact portion, and a suction portion. An undersurface of the solder bonding portion is a solder bonding face which is to be solder bonded to the conductor pattern. The elastic contact portion is connected to one end of the solder bonding portion and bent over the solder bonding portion. When in contact with a conductive member, the elastic contact portion is pressed against the conductive member while being elastically deformed. The suction portion is connected to the solder bonding portion independently of the elastic contact portion. The suction portion is made a suction face for a suction nozzle of an automatic mounter, with its top end being arranged in parallel to the undersurface of the solder bonding portion on the conductive member side of the elastic contact portion.

Abstract:
A connection electrode that is formed of solder on an electronic component side and a tip portion of an elastic contact each other at a contact portion. Regarding the elastic contact, a resistive layer is formed in the tip portion, and the tip portion is placed in a clearance of an induction coil. When a predetermined high-frequency current is passed through the induction coil, electromagnetic induction causes the resistive layer to generate heat. Solder that forms the connection electrode is melt, and flows onto the tip portion of the elastic contact. Thus, the tip portion of the elastic contact and the connection electrode can be strongly bonded together at the contact portion that is a single point therebetween.
