A stereoscopically connected structure is made up of a first circuit board and a second circuit board which are mounted with other electronic components, and a relay board having a recess which is mounted with an electronic component and is provided with a lead-out wiring extending from the electronic component, and also having a land part to be connected with the lead-out wiring on one of the surfaces of the relay board that face the first circuit board and second circuit board. Thus the relay board can mount the electronic component thereon as well as connect the first circuit board and the second circuit board, thereby achieving high density mounting.

A first printed board on which a ground pattern is provided and an electronic part is mounted and a second printed board on which a ground pattern is provided and an electronic part is mounted are oppositely arranged, and circuits of the first printed board and the second printed board are connected by a connector with a frame-like shield. In the connector with a shield, a frame body is formed of an insulator such as a resin, a connection terminal is provided inside the frame body, and a conductor is provided on the entire outer periphery of the frame body. In the conductor, the shield is formed by both the ground pattern of the first printed board and the ground pattern of the second printed board. The frame body shields the electronic parts.

Electronic circuit device (100) is structured so that a substrate module unit that are formed by stacking substrate modules made of a first resin sheet with electronic component (190) embedded thereinto is inserted into housing (150) including connecting terminal (120), control circuit (130), and first wiring pattern (140), where the substrate modules are connected to each other electrically and mechanically. This electronic circuit device (100) dispenses with a mother substrate. Further, with slimming down of a substrate module, a substrate module unit with a large number of substrate modules stacked can be loaded in a limited packaging space, thus mounting greater storage capacity and higher functionality.

An electronic module 10 includes: a circuit board 12 having a first surface and a second surface opposite the first surface; and a plurality of electronic components 14 mounted thereon. The electronic components 14 are sealed at the first surface of the circuit board 12, with a mold body 16 composed of a resin composition. A shield layer 28 is formed on the surface of the mold body 16. The glass transition temperature of a resin included in the mold body 16 is higher than the glass transition temperatures of resins included in the circuit board 12 and the shield layer 28, respectively. The modulus of elasticity of the mold body at 25° C. is 10 to 18 GPa, and the thickness of the circuit board is 0.3 to 1.0 mm.
