PROBLEM TO BE SOLVED: To stabilize economical contact of a contact of each of a plus and a minus terminals to secure electric connection with a coin-shaped battery by elastic force with each electrode surface of the coin-shaped battery. SOLUTION: A point protruded part 102a is formed at a tip part of a first contact 102 of two of a first and a second contacts 102, 103 in a minus terminal 100, and a line protruded part 103a is formed at a tip part of the second contact 103, so contact of a coin-shaped battery 30 with a minus electrode surface can be simultaneously achieved by the point and line. A point protruded part 122a is formed at a tip part of a first contact 122 of two of a first and a second contacts 122, 123 in a plus terminal 120, and a line protruded part 123a is formed at a tip part of the second contact 123, so contact of the coin-shaped battery 30 with a plus electrode surface is simultaneously achieved by the point and line. |
