1. A power conversion device comprising:
a laminated coil comprising:
a plurality of planar coils arranged in a first direction along an XY plane; and
a first insulating member in a film form arranged between a pair of planar coils adjacent to each other in the first direction among the planar coils, wherein
at least one of the planar coils is wound to have a plurality of turns spaced apart from each other in a second direction along the XY plane, and
a plurality of second insulating members arranged between the turns adjacent to each other in the second direction of the at least one of the planar coils, wherein
the plurality of the second insulating members is arranged between the turns so as to be spaced apart from each other in a circumferential direction in which the laminated coil is wound,
a support:
a protruding member fixed to the support; and
a fixing member arranged at a position overlapping with the protruding member in a two- dimensional view,
wherein the laminated coil is sandwiched and fixed between the fixing member and the protruding member so as to be in contact with the fixing member and the protruding member.
