The battery holding method and structure enable contact points between a battery and terminals to be maintained invariant in location by improving a performance in holding the battery, and accordingly a stable contact resistance can be obtained. A battery holder forms a battery chamber, and the battery chamber makes a space for housing a battery inserted along a lengthwise direction thereof. The battery holder is equipped, on a side surface thereof, with a nail for pressing the battery in touch with the side surface of the battery. When the battery is inserted into the battery chamber, the nail is deformed elastically, and the resulting restoring force thereof fixes the battery in a definite arrangement in the battery chamber with a slight and eccentric displacement.
