An electric work machine includes a smaller motor. An electric work machine includes a motor including a stator and a rotor rotatable about a rotation axis, and a sensor board including a rotation sensor that detects rotation of the rotor and a plate supporting the rotation sensor. The plate includes a first surface facing an end face of the rotor in an axial direction parallel to the rotation axis and a support area receiving the rotation sensor that faces the end face, and a second surface facing at least a part of the stator. In the axial direction, a distance between the support area and the end face is shorter than a distance between at least a part of the second surface and the end face.
