A shielded connector which connects an external cable to a circuit in a shield case of a device, the shielded connector comprising: a device-side connector (30, 30A) which is fixed to the shield case; and a cable-side connector which is attached to an end of the external cable and is fitted to the device-side connector (30, 30A), wherein the device-side connector (30, 30A) includes: a device-side connection terminal which has one end connected to the circuit in the shield case and the other end fitted to a connection terminal of the cable-side connector; a device-side resin housing which accommodates and holds the device-side connection terminal and can be fitted to the cable-side connector; a device-side shield shell (33, 33A) which holds the device-side resin housing and has a case-fixing flange part which is fixed to an outer surface of the shield case by a screw in a face contact state; and a first packing which is pressed onto the outer surface of the shield case when the case-fixing flange part is fixed to the shield case by the screw to seal a space between device-side connector (30, 30A) and the shield case; wherein the device-side shield shell (33, 33A) has a mating shell fixing part which is fastened to a cable-side shield shell provided on the cable-side connector to electrically connect the device-side shield shell (33, 33A) and the cable-side shield shell, characterized in that the device-side shield shell (33, 33A) has a thick part which is formed in thick shape so as to protrude to an outer surface of the shield case beyond the projecting height of the screw, which fastens the case-fixing flange parts to the shield case, a fitting part accommodating hole penetrates a central part of the thick part and the thick part functions as a hood part to accommodate a fitting part of the cable-side connector; and wherein the mating shell fixing part is provided on the thick part. a device-side connector (30, 30A) which is fixed to the shield case; and a cable-side connector which is attached to an end of the external cable and is fitted to the device-side connector (30, 30A), wherein the device-side connector (30, 30A) includes: a device-side connection terminal which has one end connected to the circuit in the shield case and the other end fitted to a connection terminal of the cable-side connector; a device-side resin housing which accommodates and holds the device-side connection terminal and can be fitted to the cable-side connector; a device-side shield shell (33, 33A) which holds the device-side resin housing and has a case-fixing flange part which is fixed to an outer surface of the shield case by a screw in a face contact state; and a first packing which is pressed onto the outer surface of the shield case when the case-fixing flange part is fixed to the shield case by the screw to seal a space between device-side connector (30, 30A) and the shield case; wherein the device-side shield shell (33, 33A) has a mating shell fixing part which is fastened to a cable-side shield shell provided on the cable-side connector to electrically connect the device-side shield shell (33, 33A) and the cable-side shield shell, characterized in that the device-side shield shell (33, 33A) has a thick part which is formed in thick shape so as to protrude to an outer surface of the shield case beyond the projecting height of the screw, which fastens the case-fixing flange parts to the shield case, a fitting part accommodating hole penetrates a central part of the thick part and the thick part functions as a hood part to accommodate a fitting part of the cable-side connector; and wherein the mating shell fixing part is provided on the thick part. a device-side connection terminal which has one end connected to the circuit in the shield case and the other end fitted to a connection terminal of the cable-side connector; a device-side resin housing which accommodates and holds the device-side connection terminal and can be fitted to the cable-side connector; a device-side shield shell (33, 33A) which holds the device-side resin housing and has a case-fixing flange part which is fixed to an outer surface of the shield case by a screw in a face contact state; and a first packing which is pressed onto the outer surface of the shield case when the case-fixing flange part is fixed to the shield case by the screw to seal a space between device-side connector (30, 30A) and the shield case; wherein the device-side shield shell (33, 33A) has a mating shell fixing part which is fastened to a cable-side shield shell provided on the cable-side connector to electrically connect the device-side shield shell (33, 33A) and the cable-side shield shell, characterized in that the device-side shield shell (33, 33A) has a thick part which is formed in thick shape so as to protrude to an outer surface of the shield case beyond the projecting height of the screw, which fastens the case-fixing flange parts to the shield case, a fitting part accommodating hole penetrates a central part of the thick part and the thick part functions as a hood part to accommodate a fitting part of the cable-side connector;
