PROBLEM TO BE SOLVED: To improve the connecting reliability of a battery and a reed terminal. SOLUTION: Because the occurrence of an ineffective current flowing from a welding part 7 to a conductive part 9 can be suppressed as the electric resistance of a thin-walled part 10 located between them becomes greater by making a thickness of the thin-walled part 10 around the welding part 7 thinner, a more current flows for the welding in the thickness direction of a reed terminal 3 to heighten the electric resistance of the welding part 7 that increases heat generation by the electric resistance, whereby a welding nugget 69 can be made larger, and the reed terminal 3 can be welded in a state that the connecting reliability is enhanced.
