Title:
REACTOR AND MANUFACTURING METHOD FOR REACTOR
Document Type and Number:
WIPO Patent Application WO/2012/035940
Kind Code:
A1
Abstract:
A reactor (1α) is equipped with: a coil (2), which is formed by winding a winding wire (2w); a magnetic core (3) which is arranged on the inside and outside of the coil (2) and which forms a closed magnetic circuit; and a case (4) which has an opening section and a base surface (40), facing the opening section, and which houses an assembly (10) of the coil (2) and the magnetic core (3). At least the side of the magnetic core (3) which is by the opening section of the case (4) is formed from a molded and hardened body containing magnetic powder and resin. The surface of the magnetic core (3) on the side by the opening section of the case (4) is equipped with a surface layer (5) for preventing the rust of the magnetic powder. The surface layer (5) has a resin section made from the same resin as the resin of the magnetic core (3), and this resin section is formed so as to be continuous with the resin of the magnetic core (3) without any interface.
