1. An image pickup apparatus comprising:
an image sensor;
a lens; and
an electric module disposed outside the lens when viewed in a first direction extending along an optical axis of the lens,
wherein the electric module includes
a first inductor including a first terminal and a second terminal,
a first transformer including a first primary winding including a third terminal and a fourth terminal,
a second inductor including a fifth terminal and a sixth terminal, and
a second transformer including a second primary winding including a seventh terminal and an eighth terminal,
wherein the second terminal of the first inductor is connected to the third terminal of the first primary winding,
wherein the fifth terminal of the second inductor is connected to the seventh terminal of the second primary winding,
wherein when viewed in the first direction, the first inductor is wound clockwise from the first terminal toward the second terminal,
wherein when viewed in the first direction, the second inductor is wound counterclockwise from the sixth terminal toward the fifth terminal,
wherein when the first primary winding is viewed from a first axis that extends in parallel with the optical axis and intersects the lens, the first primary winding is wound counterclockwise from the third terminal toward the fourth terminal, and
wherein when the second primary winding is viewed from a second axis that extends in parallel with the optical axis and intersects the lens, the second primary winding is wound clockwise from the seventh terminal toward the eighth terminal.
