wherein,
one end surface of the heat-dissipating case is an open end surface,

the coil is wound along the cutout portions, and
the cutout portions in the heat-dissipating case are disposed distant from the core gap part so that the coil wound along the cutout portions is disposed only in a region overlapping the divided cores.
