Abstract:
1. A circuit module device comprising: a connector provided at a predetermined position on a first circuit board on which a predetermined circuit pattern is formed and electronic parts are disposed at positions which corresponds to the circuit pattern; a shield case with four faces which covers the circuit board such that the connector can be exposed to the outside; first and second cover planes which contact the shield case of four faces to form a shield for the circuit board positioned in the shield case with four faces; a second circuit board provided at a predetermined position on the first circuit board which is covered by the shield case with four faces; a connector shield structure which electrically separates a connection portion of the connector and the circuit pattern and the electronic part which is disposed at a position corresponding with the circuit pattern, the connector shield structure being formed internally with the shield case with four faces and being bent to cover the connector; and a first connection member which electrically connects the circuit pattern formed in advance on the second circuit board and the predetermined pattern on first circuit board in a connection region that is provided between the connector shield structure and the connector; wherein the second circuit board has a ground region which is formed in advance, and a second connection member which connects the ground region and the first circuit board is connected with the first circuit board in the connection region provided between the predetermined circuit pattern of the first circuit board and the shield structure and the connector.
