The second axis (L2) is located on the plane where the guide plate (21) is located or parallel to the plane where the guide plate (21) is located. The chain saw (100) comprises a front handle (31), wherein one end (311) of the front handle (31) is connected to the housing (10) and the other end (312) comprises a free end. The drive unit comprises a motor (50), which is located between the front handle (31) and a rear handle (30), and at least part of the motor (50) is at the same height as the front handle (31). A battery mounting portion (13) is formed on one side of the housing (10), and the motor (50) and the battery mounting portion (13) essentially overlap in the direction of the first axis (L1).
