PROBLEM TO BE SOLVED: To supply power to a power supply target such as a circuit board, even if a battery contact piece and an electrode of the battery are instantaneous break away due to the occurrence of vibration to the battery, in a battery terminal. SOLUTION: When positive and negative electrodes of the battery are separated from positive and negative contact parts 111, 112 of a first battery contact piece 11, by a restoring force of a following contact piece 12, a first protrusion 12a is made to follow the positive electrode of the battery B and a second protrusion 12b is made to follow the negative electrode of the battery B, and current from the battery B is energized to the armature 11 via the contact piece 12.
