A module with a built-in circuit component of the present invention includes an electric insulating layer, a pair of wiring layers provided on both principal planes of the electric insulating layer, a plurality of via conductors electrically connecting the pair of wiring layers and passing through the electric insulating layer in a thickness direction thereof, and a circuit component buried in the electric insulating layer, wherein the plurality of via conductors are disposed in a circumferential portion of the electric insulating layer in accordance with a predetermined rule. The plurality of via conductors are placed at an interval, for example, so as to form at least one straight line, in a cut surface of the electric insulating layer in a direction parallel to a principal plane thereof.
