A shielded connector structure includes a first connector and a second connector, each having a metal terminal element, an insulating connector housing that has a terminal container for accommodating the metal terminal elements, and a conductive shield shell which covers the terminal container of the connector housing. The shielded connector structure further includes a conductive connector mounting portion which contacts the shield shell of at least one of the first and second connectors to ground the shield shell; and a connecting portion which is provided on each of the shield shells of the first and second connectors, and is coupled to the connector mounting portion when the first and second connectors are engaged to shield-connect the shield shells each other.
