A stator core of an electric motor includes a core body, a slot, and an insulating member. The insulating member is integrated with the core body and has a linear expansion coefficient different from the core body. The insulating member includes, at a peripheral wall portion, a plurality of contact portions extending throughout a cylinder axial direction of the stator core and being in contact with the peripheral wall portion, and a noncontact portion positioned between adjacent ones of the contact portions. The noncontact portion extends throughout the cylinder axial direction and is not in contact with the peripheral wall portion. The peripheral wall portion has an inner peripheral wall portion forming a peripheral wall of the slot, and an outer peripheral wall portion forming an outer peripheral wall of the core body. The insulating member is located at at least one of the inner and outer peripheral wall portions.

For an electronic circuit apparatus including a shunt resistor, provided is a measure for improving the heat dissipation performance of the shunt resistor. The shunt resistor includes electrodes at both ends. One of the two electrodes is connected to a surface-mounting pattern on which the shunt resistor is surface-mounted. A current-generating-side pattern and a current-receiving-side pattern are arranged separately from the surface-mounting pattern. The current-generating-side pattern and the surface-mounting pattern are connected together via a connection member which creates a space between itself and a substrate.
