Claim:
1. A button cell terminal to electrically connect a circuit board and a button cell in which one direction along a plane direction of the button cell is defined as an X-axis direction, a direction along the plane direction and perpendicular to the X-axis direction is defined as a Y-axis direction, and a direction perpendicular to the X-axis direction and the Y-axis direction and along a thickness direction of the button cell is defined as a Z-axis direction, the button cell terminal comprising: a spring contact terminal that is pressed by an outer circumferential surface of a positive electrode of the button cell, and is arranged into a spring shape that elastically deforms in accordance with a pressing force exerted from the button cell in the X-axis direction and in the Z-axis direction; a board joint that is joined to the circuit board; and a pressing force absorbing spring portion that is arranged between the board joint and the spring contact terminal so as to be elastically deformable, and absorbs the pressing force of the button cell received at the spring contact terminal through elastic deformation regardless of presence or absence of a cell holder defining a position of the button cell, wherein: the pressing force absorbing spring portion has a distal end portion connected to the spring contact terminal, and includes a bent arm arranged into a spring shape that elastically deforms in accordance with the pressing force from the button cell in the X-axis direction and in the Y-axis direction to absorb the pressing force from the button cell; and the spring contact terminal is arranged as a pair of spring contact terminals arranged in the Y-axis direction, and is in contact with different parts of the outer circumferential surface of the positive electrode of the button cell.
