PROBLEM TO BE SOLVED: To improve the reliability of an apparatus by preventing the generation of cracks in solder of a fixing part, and by controlling the generation of stress on a fixing part of a power source terminal. SOLUTION: A power source terminal 18 has its contact part 9 brought into contact with a battery electrode 2a and also has its arm 10 fixed to a board 15. A middle part between the contact part 9 of the power source terminal 18 and the arm 10 is interfit to a slit 16 carved on the board 15. The flexure of the power source terminal 18 is tied up with an interfit part of the slit 16 so that the displacement acting on the contact part 9 does not affect a fixing part of the board 15 of the power source terminal 18. |
