A motor wiring structure of the present invention relates to motor wiring for supplying electric power to coils which are respectively wound around split cores provided in a stator. The motor wiring structure includes a power supply-side terminal disposed on a power supply side, multiple coil connection-side terminals configured to be connected respectively to winding wire terminals of the coils, and multiple conductor wires each independently connecting the power supply-side terminal and one of the multiple coil connection-side terminals to each other. Moreover, the motor wiring structure includes a positioning and heat-dissipating protrusion which is provided to the coil connection-side terminal, and which is configured to position the coil connection-side terminal with respect to the stator and dissipate heat during thermal crimping with the coil.
