Provided is a circuit board including: a board main body; a positive electrode-side power supply terminal part of the circuit part, which is formed on the board main body and is connected to the positive electrode terminal; and a negative electrode-side power supply terminal part of the circuit part, which is formed on the board main body and connected to the negative electrode terminal. The board main body having a first through-hole, a second through-hole, and a third through-hole that penetrate the board main body in the thickness direction; the first through-hole and the second through-hole being provided on the outer end side of the board main body compared to the third through-hole. The circuit part is provided with a first capacitor and a second capacitor connected in series between the positive-electrode-side power supply terminal part and the negative-electrode-side power supply terminal part, and the circuit board is further provided with a conductor part formed in at least a part of the third through-hole, the conductor part being electrically connected to the positive-electrode-side power supply terminal part via the first capacitor, and the conductor part being electrically connected to the negative-electrode-side power supply terminal part via the second capacitor. At least a portion of the conductor part is a conductor and is electrically connectable to a unit on which the board main body is mounted.
