An electric work machine (1; 201) includes: a motor housing (6; 212) having a tube part (6C; 212C) and a bottom part (6M; 212M); a brushless motor (5; 228) having a stator (20), which has a first contact surface (58F; 258F), and a rotor (21; 231) disposed in the stator; a baffle plate (25; 285); and an output shaft (31; 292). The stator includes a tube-shaped stator core (50) having a ring-shaped second contact surface (50S; 250S) that is opposite of the first contact surface, and coils (56; 256) wound on the stator core. The stator is held by the motor housing with the first contact surface in contact with the bottom part. A protruding part (25S; 285S) of the baffle plate contacts the entire circumference of the second contact surface of the stator core and is fixed to the motor housing by three or more screws (68; 288).
