PROBLEM TO BE SOLVED: To provide a high-input and long-life stator with its cooling performance and work efficiency improved, and furthermore a power tool comprising the same. SOLUTION: A coil end 3 protruding in bundle from both ends of a stator core 6, among the stator coils wound in the slot of the stator core 6, is tightly fitted with a part of metal material component 1 while a part of the metal material component 1 is exposed to the outside air, thus the heat generated at the coil end 3 is released through the metal material component 1.
