PROBLEM TO BE SOLVED: To improve workability and stabilize quality. SOLUTION: Each end section 1a of fuse line 1 that is composed of the fusible material of low melting point is brought into contact with each terminal section 10 set opposite to a lead frame 10 consisting of the metal material of high melting point. Each terminal section 10a of the lead frame 10 is irradiated from the opposite side of the fuse line 1 by two beams of a laser beam 12 and each terminal 1a of the fuse line 1 is connected at the terminal secession 10a by heating and fusing by heat transfer from the lead frame 10. |
