One aspect of the present disclosure provides an electric work machine with which a housing and a brushless motor are provided. The brushless motor (i) is housed in the housing and (ii) includes a stator and a rotor. The rotor includes a rotor core, permanent magnets, and a resin fixing portion. The permanent magnets are (i) spaced apart from each other in a circumferential direction of the rotor core and (ii) arranged such that like poles thereof are aligned along the circumferential direction. The resin fixing portion is in contact with the rotor core and the permanent magnets, thereby to integrally fix the permanent magnets to the rotor core via the resin fixing portion.
