Provided is an electronic part that includes a first substrate including a first base and a first coil, the first coil being electrically insulated from the first base, a second substrate including a second base and a second coil, the second coil being electrically insulated from the second base, and a support member that supports the first substrate and the second substrate. The first substrate is arranged between the second substrate and the support member in a thickness direction of the support member and overlaps the second substrate as viewed in the thickness direction, the first base is positioned between the first coil and the second coil in the thickness direction, and the first coil and the second coil are magnetically coupled.
