PROBLEM TO BE SOLVED: To provide a method for manufacturing a printed wiring board with a metal dome which is of low cost and excellent in bending property and flexibility. SOLUTION: There are provided an annular first electrode wiring part 20 which is formed on a base substrate 10 on which a springy metal dome 50 is placed, a second electrode wiring part 30 formed in the annulus of the wiring part 20, and a rear-surface wiring part 40 which is formed on the rear surface side of the base substrate 10 and connected to the wiring part 30 through a through hole 10a. After the circuit pattern of the wiring parts 20 and 30 on the base substrate 10 is formed, the through hole 10a is opened from the rear surface side of the base substrate 10 to the second electrode wiring part 30 by laser-working, and through it, the rear-surface wiring part 40 is formed by silver-paste printing across the rear surface side of the base substrate 10. Thus, excellent bending property and flexibility are provided at a low cost.
