PROBLEM TO BE SOLVED: To provide a joint method for a printed-wiring board that can prevent disconnection at a junction due to heat distortion and transformation of a printed-wiring board, and can secure reliability of a joining terminal as well as electronic devices. SOLUTION: This is a joint method for a printed-wiring board that uses solders 6 and 6c to join copper foil terminals 3 and 3a of a first printed-wiring board 1 and those of a second printed-wiring board 5. The copper foil terminals of the first and second printed-wiring boards include a copper foil terminal 3a in which a through-hole 4 is formed that passes through the first or second printed-wiring board 1 or 5, a solder 6c filled in the through-hole 4 is used to join the copper foil terminals 3a in which the through-hole 4 is formed.
