A flat-type shielded cable includes a plurality of signal wires 21, each having an insulating covering member, and a drain wire 22, which are juxtaposed to one another in closely-contacted relation to one another, a shielding layer 23, and an insulating sheath 24, the shielding layer and the insulating sheath sequentially covering an outer periphery of the juxtaposed wires. This cable is characterized in that an outer diameter of the signal wire 21 is in a range of 1.25 mm to 1.4 mm, and an cross-sectional area of a conductor 21a of the signal wire 21 is 0.03 to 0.09 mm2, and the insulating covering member 21b of the signal wire 21 is made of an insulative material having a dielectric contact of 1.7 to 2.8, and a characteristic impedance of the signal wire 21 is 75OMEGA (±10%).
