Electric working machine

An electric working machine comprising:

• a motor including:
• a case including a central axis,
• a shaft oriented along the central axis,
• a first motor terminal protruding from a front face of the motor, and
• a second motor terminal protruding from the front face of the motor, and located opposite the first motor terminal with respect to the central axis;
• a fixing tool configured to fix onto the case, and configured to pass the first and second motor terminals without contacting them, wherein the fixing tool includes:
• a mount surface,
• an internal thread orthogonal to the mount surface,
• a first central hole coaxial with the shaft and configured to pass the shaft;
• a circuit board configured to mount onto the mount surface and including:
• a screw hole aligned with the internal thread,
• a first cutout configured to pass the first motor terminal,
• a second cutout configured to pass the second motor terminal,
• an attachment extending radially beyond the case,
• a second central hole coaxial with the shaft and configured to pass the shaft,
• five conduction patterns located on a front surface of the circuit board, the five conduction patterns including:
• a ground connection member surrounding:
• the screw hole, and the second central hole,
• a first terminal-connecting part located adjacent to the first cutout and adjacent to the ground connection member,
• a second terminal-connecting part located adjacent to the second cutout and adjacent to the ground connection member,
• a first input terminal member located adjacent to the ground connection member and located at least partly on the attachment, and
• a second input terminal member located adjacent to the ground connection member and located at least partly on the attachment.
