Abstract:
1. An electronic circuit module, comprising: a substrate with built-in component; a mount component mounted on the substrate with built-in component; a sealing portion covering the mount component; and a shield made of a conductive synthetic resin covering the sealing portion, the substrate with built-in component having a core layer made of a metal also functioning as ground wiring, an outer cover made of an insulating synthetic resin covering a side face of the core layer, and a first protrusion integrated with the core layer that protrudes outwardly from the side face of the core layer and has an end face exposed at the outer cover, a face of the first protrusion facing to an end face of the shield being adjacent to a face of the outer cover facing to the end face of the shield, and the end face of the shield bonded to both of the face of the first protrusion facing to the end face of the shield and the face of the outer cover facing to the end face of the shield.
