To provide an electronic circuit that has an interposer (rewiring layer) inserted therein and an asynchronous receiver capable of properly receiving a signal. An electronic circuit includes: a first substrate having a first coil that is formed by a wire and transmits a signal and a first transmission circuit that is connected to the first coil and asynchronously outputs the signal to the first coil; a second substrate having a second coil that is formed by a wire at a position corresponding to the first coil and forms a communication channel with the first coil to receive the signal and a third coil that is connected to the second coil by a wire on the substrate and transmits the signal; and a third substrate having a fourth coil that is formed by a wire at a position corresponding to the third coil and forms a communication channel with the third coil to receive the signal and a first reception circuit that is connected to the fourth coil and asynchronously receives the signal, the first substrate, the second substrate and the third substrate being stacked on one another, and the first transmission circuit changes a current that is to be made to flow to the first coil each time a logical value of transmission data changes.
