Claims

[Scope of Claim for Utility Model Registration] In an electronic circuit shield structure in which a plurality of circuits are mounted on a wiring board, the wiring board is housed in a shield case, and the circuits of the wiring board are mutually shielded, The case consists of two case halves, the periphery of the wiring board is sandwiched between these case halves, and a ground layer is formed on the wiring board between the portions sandwiched by the case halves and the circuits to be shielded from each other. A connection line connecting the circuits is formed on the wiring board, a plurality of connectors connected to the circuits are attached to the wiring board, and a hole is made in the case corresponding to each connector. The connector faces the outside through the hole so that it can be connected to the outside, and partition walls are formed integrally with each of the case halves to correspond to the ground layer in the circuit that should be shielded from each other, and are in shield contact with the ground layer. Electronic circuit shield structure.
