PROBLEM TO BE SOLVED: To provide a winding component in which heat dissipation is enhanced while achieving compaction, and to provide a power supply device.SOLUTION: A winding component 1A includes: a pair of magnetic material cores 5A, 5B facing each other; a coil winding 20 formed of a planar conductive material, and having a coil part and terminal parts provided at both ends of the coil part; a housing 70 for dissipating heat from the coil winding 20; and heat transmission members 60, 61 arranged between the coil winding 20 and the housing 70. The coil part has a flat plate part held by the pair of magnetic material cores 5A, 5B, and a bending part extending from the flat plate part toward the housing 70 side at a position not overlapping the magnetic material cores 5A, 5B, in the plan view. The heat transmission members 60, 61 are in contact with the housing 70 and the bending part. |
