<p>A chain saw (100) as a power tool comprises a combustion engine (111) and an electric motor (141) . The chain saw (100) has a driving shaft (131) which drives a saw chain (105), a battery pack (137) which provides electric current to the electric motor (141), a controller (139) which is connected to the battery pack (137), and a sensor (162, 163) which detects a driving state of a driving mechanism including the combustion engine (111) and the electric motor (141) . In the chain saw (100), the saw chain (105) is driven in a hybrid driving mode in which both the combustion engine (111) and the electric motor (141) drive the driving shaft (139). Further, the controller (139) controls a driving of the combustion engine (111) based on a detection result of the sensor (162, 163).
