Abstract:
This method for manufacturing a reactor (10) includes: an assembly manufacturing step for assembling a core-coil assembly provided with a reactor core (20), which comprises an inner-side core part that extends in a first direction and an outer-side core part that extends in a second direction and is linked to the inner-side core part, and a coil (30) that can be disposed around the inner-side core part with a gap therebetween and is wound in a tubular shape extending in the first direction, the external dimensions of the coil (30) in a third direction being configured to correspond to the external dimensions of the outer-side core part in the third direction; an installation step for installing the core-coil assembly in a mold in an orientation in which the third direction extends upward and downward so that the position of the lowermost part of the coil (30) in the third direction and the position of the lowermost part of the outer-side core part coincide; and an injection molding step for filling at least the gap with an insulating material by injection molding.
