<P>PROBLEM TO BE SOLVED: To provide a reactor in which vibration can be reduced by suppressing peeling between a columnar member and a core. <P>SOLUTION: A reactor 1 includes: a cylindrical coil 2 which generates a magnetic flux by energization; a columnar member 4 arranged in an axial direction X of the coil 2, on the inner peripheral side of the coil 2; and a core 3 made of a magnetic powder mixed resin obtained by mixing a magnetic powder with an insulating resin. The coil 2 and the columnar member 4 are embedded in the core 3. On a contact surface of the columnar member 4 with the core 3, a recess 51 whose inner surface 511 is spherical is formed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
