The electric circuit includes a first inductor and a third inductor that, when viewed in plan view from a first direction, wind around a first axis extending in the first direction, and a second inductor that, when viewed in plan view from the first direction, winds around a second axis extending in the first direction. A second region where the second inductor is provided overlaps, in the first direction, with a first region where the first inductor is provided or a third region where the third inductor is provided. When a common mode signal is inputted to the first inductor to third inductor, the orientation of a magnetic field produced in the first axis by the first inductor and the third inductor is opposite from the orientation of a magnetic field produced in the second axis by the second inductor.
