It is an object of the invention to provide an effective technique for reducing the load of user's fingers in a power tool. A representative power tool (100) includes a body (101), a tool bit (110), a driving means (120) and a handgrip (130) that extends from a grip proximal end (130a) on the side of the body to a grip distal end (130b) in a direction that crosses the axial direction of the tool bit. In the handgrip first (135), second (136), third (137), fourth (138), fifth (139) grip regions are defined as regions in which fingers are positioned when holding the handgrip. The cross sections of the handgrip in the first to fifth grip region are configured to be oval. The body has a casing made of hard material and a cushion of a material softer than the hard material being provided around the casing.
