PURPOSE:To always stabilize connection of an electromagnetic wave shielding layer to a ground circuit by forming an insulating layer of a plurality of insulating layers, gradually increasing in diameter the openings of the ground circuits of the layers toward the layers of the shielding layers. CONSTITUTION:In order to form insulating layers 3a, 3b, and 3d on the upper side of a printed wiring circuit 2, the diameter of the opening of a terminal 5 to be formed at the upper side of a ground terminal 4 of the circuit 2 is gradually increased in diameter from an underresist 3a of the circuit 2 side toward an underresist 3c of an electromagnetic wave shielding layer 6 side with respect to the diameter of the terminal 4 to form an opening of the terminal 5 made of a cuplike recess at the upper side of the terminal 4. The resist 3 is coated with conductive paste such as thermosetting paste by a silk printing method, etc., thereby forming the layer 6. |
