Claim Text:
1. A reactor, comprising: a coil including a hollow core-insertion part; and a core unit comprising a plurality of partial cores butted one another to form a closed magnetic path, and partially inserted and disposed in the hollow core-insertion part of the coil, the plurality of partial cores comprising a first partial core which forms a magnetic path passing through the hollow core-insertion part of the coil and has a pressed face surface pressed at a time of press-shaping; and a second partial core which forms a magnetic path passing through an exterior of the hollow core-insertion part of the coil and has a pressed face surface pressed at a time of press-shaping, the first partial core inserted and disposed in the hollow core-insertion part of the coil such that the pressed face surface of the first partial core is oriented orthogonal to a winding axis direction of the coil, the second partial core butted against the first partial core and disposed such that the pressed face surface of the second partial core is oriented orthogonal to the pressed face surface of the first partial core, and the pressed face surface of the second partial core being a substantially flat plane, wherein the first partial core comprises a first magnetic path end face orthogonal to the winding axis direction, the second partial core comprises a second magnetic path end face orthogonal to the winding axis direction, and the first magnetic path end face and the second magnetic path end face are disposed so as to face each other, and to have different area sizes between each other.
