PROBLEM TO BE SOLVED: To provide an integrated LNB, capable of controlling an interval between a horizontally polarized wave input part and a vertically polarized wave input part. SOLUTION: The horizontally polarized wave receiving part (H) is composed of a rectangular waveguide 1a of a first conductive member 1 for inputting a horizontally polarized wave, a probe 4a for receiving horizontally polarized wave provided on a circuit board 4 for receiving radio wave and a rectangular recessed part 2a of a second conductive member 2 for terminating the rectangular waveguide 1a. The vertically polarized wave receiving part (V) is composed of a first rectangular waveguide 3a composed of a first rectangular recessed part 3a of a third conductive member 3 for inputting a vertically polarized wave, a second rectangular waveguide 3b constituted by fixing and sealing a second rectangular recessed part 3b of the third conductive member 3 to the first conductive member 1, a slot 3c for transmitting the radio waves of the first rectangular waveguide 3a to the second rectangular waveguide 3b, a probe 4b for receiving vertically polarized wave of the circuit board 4 which protrudes through an inserting hole 1b for probe of the first conductive member 1 for receiving a radio wave in the second rectangular waveguide 3b into the second rectangular waveguide 3b, and a projection 1c for termination of the first conductive member 1 for terminating the second rectangular waveguide 3b.
