Abstract

Electromagnetic shielding about both of electric connectors, which are in a mutually mated state, can be sufficiently carried out by a simple configuration. Shield wall portions composed of electrically-conductive members opposed to contact connecting portions (board connecting portions) of a plurality of contact members arranged in multipolar shapes are provided; electromagnetic shielding functions with respect to the contact connecting portions in the respective electric connectors are obtained well by the respective shield wall portions; and, when both of the electric connectors are mated with each other, the shield wall portions are configured to be in an inner/outer double disposition relation in which they are opposed to each other and efficiently block the gaps between the shield wall portions and wiring boards so that sufficient EMI measures can be expected.
