PCT No. PCT/JP98/00697 Sec. 371 Date Oct. 23, 1998 Sec. 102(e) Date Oct. 23, 1998 PCT Filed Feb. 18, 1998 PCT Pub. No. WO98/38689 PCT Pub. Date Sep. 3, 1998A battery device includes a lithium ion battery in a flattened cylindrical form and a circuit board arranged on a side surface of the battery. A first connection member connects between the circuit board and a positive pole, while a second connection member connects between the circuit board and a negative pole. The first connection member and the second connection member are both of strip members. The strip member is formed is a plurality of partial cuts extending from a lateral end of the strip member in a width direction. When there is a variation in the connection length between the circuit board and the positive/negative pole, the plurality of the partial cuts are opened or closed to thereby absorb the variation of the connection length by the first connection member and the second connection member.
