<p>PROBLEM TO BE SOLVED: To reduce a mounting area to a printed circuit board and to prevent the coming-off of a button buttery due to vibration. SOLUTION: A rectangular opening 3a is formed in a frame body 3 of this battery holder 2, a stopper 7 is mounted on one side of the entrance of the opening 3a, and a slope is formed on the stopper 7. In the inside of the opening 3a, a contact terminal part 5b of a negative electrode-side contact terminal 5 is housed on one side thereof, a contact terminal part 6b of a positive electrode-side contact terminal 6 is oppositely disposed on the other side thereof, and a negative electrode terminal soldering part 5a at the lower end of the contact terminal 5 and a positive electrode terminal soldering part 6a of the contact terminal 6 are soldered to a pattern of a board 4. The button battery 1 is inserted into the opening 3a while inserting its positive electrode terminal 1b into the opening 3a along the slope of the stopper 7 and bringing a positive electrode terminal 1c on the side face into contact with the contact terminal 5b and by changing its attitude vertically.</p> |
