PROBLEM TO BE SOLVED: To provide a battery pack controlling the action of an existing electric tool by adding a simple control circuit to the battery pack, and also to provide a cordless electric tool using the battery pack as a power supply. SOLUTION: The action to be controlled of the electric tool is controlled by a control means in the battery pack 1 by providing a factor to be detected related to the action to be controlled of the electric tool, for example, an acceleration sensor for detecting the hitting and the control means (a microcomputer), which controls the target action of the electric tool by receiving the detected output of the acceleration sensor, in the battery pack 1.
