PURPOSE: To realize highly reliable connection by regulating the output, diameter, number of pulses and time of a laser beam being projected to a region and the end part of a conductor arranged thereon such that a defect for decreasing the electric resistance is generated at a part of a dielectric layer. CONSTITUTION: An end part 15a of a conductor 15 is arranged on a region 12 in order to form a connection 19 between them using a beam laser 20. The beam laser 20 having diameter D, output P and pulse time T is projected in the direction intersecting the upper surface 11a of a substrate 11 perpendicularly such that the impact zone 21 thereof is divided into a region 21a above the end part 15a and a region 21b above a dielectric layer 13. The output P, diameter D, number N and duration T of pulses of the beam laser 20 are regulated such that a defect for decreasing the electric resistance is generated at the connecting part 19 of the dielectric layer.
