1. A reactor comprising:
a laminated core formed of a plurality of soft-magnetic ribbons that are laminated in a lamination direction; and a coil wound around the laminated core, wherein the laminated core has a gap that is formed in the laminated core across a magnetic path direction along which magnetic flux flows in the laminated core, the laminated core also has a flat facing surface that faces the gap and a pair of flat side surfaces that are respectively on opposite sides of the facing surface in the lamination direction, the laminated core further has a pair of first corner curved surfaces that are respectively formed between the facing surface and one of the side surfaces and between the facing surface and the other side surface, each of the first corner curved surfaces has a width in the lamination direction greater than a thickness of each of the soft-magnetic ribbons forming the laminated core, and for each of the first corner curved surfaces, a length of the first corner curved surface in the magnetic path direction is greater than the width of the first corner curved surface in the lamination direction. |
