Claim 16:
17. A reactor comprising:
a first case shaped to form a part of a closed loop, the first case having an outer frame;
a plurality of first core pieces disposed inside the first case;
a second core piece disposed to form a closed magnetic path together with the first core pieces inside the first case, the closed magnetic path having a closed loop shape; and
a coil wound around the closed magnetic path, wherein
a plurality of partitions are arranged inside the outer frame to separate an accommodating region in which the first core pieces are disposed,
the first case accommodates at least a part of the second core piece such that, at a first end portion of the first case in a first direction in which the first core pieces are arranged, at least a part of the second core piece is accommodated in the first case so as to extend in a second direction intersecting the first direction,
the first case is provided with an opening through which the second core piece is introduced and removed in the second direction, the opening being located in at least one of outermost portions of the first case that are adjacent to a second end portion in the second direction in the second core piece accommodated in the first case, and
the accommodating region is larger than the first core pieces in a plan view so as to allow the first core pieces to move in an extending direction of the closed magnetic path.
