REACTOR AND REACTOR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reactor which can reduce and relax stress loaded to a magnetic core and has excellent manufacturability, and also to provide a reactor manufacturing method.SOLUTION: A reactor includes: a coil 2A; a plurality of core pieces 30A; a foaming resin gap material 35A interposed between at least one set of core pieces; and a magnetic core 3A for forming a closed magnetic circuit in accordance with magnetization of the coil 2A. At least one foaming resin gap material 35A includes a foaming resin part 35 constituted of foaming resin in a contact zone with the core piece.SELECTED DRAWING: Figure 1
