1. A magnetic component comprising:
a core unit comprising an upper core and a lower core;
a bobbin unit having at least a portion disposed inside the core unit; and
a coil unit comprising primary coils and secondary coils disposed to be spaced apart from each other on the bobbin unit in a second direction, the second direction being perpendicular to a first direction oriented from the upper core toward the lower core,
wherein the bobbin unit comprises:
a wound portion including an upper flange portion, a lower flange portion spaced apart from the upper flange portion, and a middle flange portion connecting the upper flange portion and the lower flange portion;
a first terminal accommodation portion extending in the second direction from the upper flange portion; and
a second terminal accommodation portion extending in the second direction from the lower flange portion,
wherein one side of the first terminal accommodation portion includes a plurality of first terminal pins bent in the first direction,
wherein one side of the second terminal accommodation portion includes a plurality of second terminal pins bent in the first direction
wherein at least a part of the secondary coils is electrically connected to the plurality of first terminal pins in the second direction through the wound portion,
wherein a last part of the secondary coils is electrically connected to the plurality of second terminal pins in the second direction through the wound portion, and
wherein the bobbin unit includes an insulative reinforcement portion exposing the plurality of first terminal pins and the plurality of second terminal pins.
