PROBLEM TO BE SOLVED: To provide a method of bonding metal wire by which a metal wire can be bonded to electrodes, without lowering the breaking strength of the wire nor bringing the front end portion of a bonding tool into collision with the base structures, etc., of the electrodes and the bonding spots and bonding operation can be monitored fully. SOLUTION: This method includes a first step of bonding the metal wire 15 to electrodes provided at both ends of the wire 15 through wedge-bonding method, a second step of cutting the wire 15, and a third step of bonding the intermediate section of the wire 15 to an electrode provided at a mid-point by the press-bonding method to connect three or more electrodes to each other through one metal wire 15. |
