Abstract
Provided are a core and coil molding structure and a manufacturing method thereof which are capable of eliminating a void between coil layers to prevent foreign materials from entering therein, and which improve the vibration resistance and shock resistance of a reactor. A core and coil molding structure includes a coil that is a rectangular coil, a core yoke member in a block shape, and a resin member molding at least a part of those. The presence of a positioning member in a pin shape which positions the coil within a mold forms a groove in the inner circumference of the coil in the resin member.
