Provided is a circuit module having less noise, and an inverter using the same. The circuit module 2 is provided with a circuit part 4, an input terminal part 5, an output terminal part 6, and a support 21. The circuit part 4 includes a conversion circuit, and a switch circuit. The output terminal part 6 includes a first output terminal 61 and a second output terminal 62 that are respectively electrically connected to a pair of output points of the circuit part 4. The arrangement of the output terminal part 6 on one surface of the support 21 is such that the first output terminal and the second output terminal are positioned around the circuit part 4 on the same side with respect to the circuit part 4, or the first output terminal and the second output terminal are adjacent to one another around the circuit part 4.
