Provided are: a circuit board that can increase the operational stability of a mounted circuit; and an electronic device that uses the circuit board. The circuit board (1a) is provided with: a metal substrate (2); an insulating layer (3) provided to one surface of the metal substrate (2); and a conductor layer (4) provided on the insulating layer (3). The conductor layer (4) is provided with a wiring pattern having: switching arm series circuit terminal groups (41U, 41V, 41W) configured from a plurality of switching element terminals for connecting switching elements; and drive circuit terminal groups (42U, 42V, 42W) configured from a plurality of drive circuit terminals for connecting drive circuits that impose a driving voltage on the switching elements. The switching arm series circuit terminal groups (41U, 41V, 41W) and the drive circuit terminal groups (42U, 42V, 42W) are formed on the same surface. |
