Magnetic component unit

A magnetic component unit, comprising:

• a coil component having a magnetic core;
• a heat dissipator on which the coil component is mounted and which has an engagement fixing portion and a press fixing portion and is made of metal;
• and
• a magnetic core fixing portion made of metal and including a holding portion that presses against the coil component, an engaging portion that extends from a first end part of the holding portion toward the heat dissipator and has a turned-back end part, and a pressing portion that extends from a second end part of the holding portion toward the heat dissipator and has an end part bent into an L-shape, wherein
• the engagement fixing portion has a U-shape, and one end and another end of the engagement fixing portion are connected to a peripheral edge portion of the heat dissipator,
• the engagement fixing portion is provided protruding from the peripheral edge portion of the heat dissipator in a first direction perpendicular to a mounting surface of the heat dissipator,
• the engagement fixing portion engages the engaging portion,
• the press fixing portion has a columnar shape and is provided protruding from the heat dissipator in the first direction,
• the press fixing portion has a fixing hole punched in the first direction,
• the pressing portion has a through-hole punched in the first direction,
• the press fixing portion and the pressing portion are joined together by a fixing tool inserted through the through-hole and the fixing hole, and
• the coil component is held between the holding portion and the heat dissipator.
