There is provided an electronic circuit module that prevents a bonding force between ground wiring and a shield from decreasing and maintains successfully a desirable shield effect. The electronic circuit module includes a core layer also functioning as the ground wiring, each face OS of each first protrusion of the core layer facing to an end face of a shield is adjacent to faces OS of an outer cover made of an insulating synthetic resin facing to the end face of the shield, and the end face of the shield is bonded to both of the each face OS of each first protrusion facing to the end face of the shield and the faces OS of the outer cover facing to the end face of the shield.
