Circuit board, motor driving apparatus, and electric power steering apparatus

A circuit board provided on one side of a motor in a direction in which a shaft extends to control the motor, the motor including three or more phases and a stator including at least a first winding and a second winding, a rotor rotatable relative to the stator, and the shaft rotatable with the rotor, the circuit board comprising:

• a power supply terminal connection assembly to which current is supplied from an external power supply;
• a first motor circuit that generates current to be supplied to the first winding from the current supplied to the power supply terminal connection assembly;
• a first motor terminal connection assembly that supplies the current generated by the first motor circuit to the first winding;
• a second motor circuit that generates current to be supplied to the second winding from the current supplied to the power supply terminal connection assembly;
• a second motor terminal connection assembly that supplies the current generated by the second motor circuit to the second winding;
• a first region in which the first motor circuit and the first motor terminal connection assembly are located;
• and
• a second region in which the second motor circuit and the second motor terminal connection assembly are located;
• wherein
• the power supply terminal connection assembly is located in the first region or the second region on a side of one end portion of a border line between the first region and the second region;
• and
• the first motor terminal connection assembly and the second motor terminal connection assembly are located on a side of another end portion of the border line.
