1. A coil component used for two-phase transformer coupling, the coil component comprising:
a first coil and a second coil; and
a magnetic core at which the first coil and the second coil are provided,
wherein
the magnetic core comprises:
a first magnetic leg at which the first coil is provided, the first magnetic leg comprising first divided core pieces;
a second magnetic leg at which the second coil is provided, the second magnetic leg comprising second divided core pieces;
a central leg portion interposed between the first magnetic leg and the second magnetic leg;
a pair of connection portions connecting the first magnetic leg, the central leg portion, and the second magnetic leg in parallel;
a main gap interposed in the central leg portion;
a first gap interposed in the first magnetic leg; and
a second gap interposed in the second magnetic leg,
the main gap, the first gap, and the second gap have a relationship where a coupling coefficient between the first coil and the second coil is greater than 0.7,
the first divided core pieces are spaced from each other in accordance with a first gap length,
the second divided core pieces are spaced from each other in accordance with a second gap length, and
each of the first gap length and the second gap length is shorter than a gap length of the main gap.
