PROBLEM TO BE SOLVED: To provide an in-vehicle power conversion device capable of suppressing increase in calorific value in a coil member even upon energization of a large current, and capable of reducing in size by achieving a low-profile coil member.SOLUTION: A laminated coil 11 is manufactured in the shape of a ring by integrally bonding conductor wiring 12, 13 formed by shaping a sheet-shaped metal conductor in a spiral coil pattern and an insulating film 14 formed of an insulating resin in an overlapping manner. The laminated coil 11 forms a coil member of a transformer, a resonance coil, or the like applied to an in-vehicle power conversion device. |
