PROBLEM TO BE SOLVED: To provide a high-frequency signal receiver which sets individual semiconductor chips 2, 3 serving as a tuner circuit in a place for enhancing the high-frequency isolation of the chips. SOLUTION: A first and second semiconductor chips 2, 3 constituting a tuner circuit are disposed on a circuit board 1 having a plurality of connecting terminals 5, and a common circuits 4 to both the semiconductor chips 2, 3 is disposed between both chips 2, 3 that one side, having receiving RF signal input lead terminals faces the outside of the circuit board 1, and the opposite side to the one side, having lead terminals connected to the common circuit 4 faces the common circuit 4. Among the plurality of connecting terminals 5 of the circuit board 1, the connecting terminals 5 at both sides are connected to the receiving RF signal input lead terminals of the first and second chips 2, 3 through a connection circuit pattern.
