To provide a power tool that achieves high power by suppressing temperature rise in a stator without incurring increase in the number of parts or the size of a motor.

The power tool is obtained by: placing a motor as a driving source in a housing; combining and integrating multiple split stators to construct the cylindrical stator of the motor; and constructing each split stator of a split stator core 22A and a stator coil 24 obtained by winding a flat conductor 23 on its magnetic pole 22a. The flat conductor 23 is so formed that its sectional shape is a fan-like shape by setting it so that the following is performed: when a section of the flat conductor 23 comprising the stator coil 24 is viewed to the extent that it is included in the split stator core 22A, the length L2 of the farthest side 23b of the circumference of the section from the central axis of the stator in the radial direction is greater than the length L1 of the closest side 23a (L2L1).
