PROBLEM TO BE SOLVED: To obtain a light receiver for transducing the intensity of light into an electric signal in which polarization dependency is controlled with high accuracy. SOLUTION: The light receiver is provided with a light receiving element 5 receiving an incident light on a specified light receiving face, a first rotary holder 2 disposed in front of the light receiving face 5a and having a first through hole 2a for passing the incident light provided with a counterbore part 2b where the direction of central axis is inclining by a first angle against the optical axis of the incident light, a second rotary holder 3 being fixed to the first rotary holder 2 when it is fitted rotatably to the counterbore part 2b and having a second through hole 3b for passing the incident light where the opening end face 3c on the incident side is inclining by a second angle at the second through hole 3b, and a light transmitting plate 3 provided at the opening end face 3c on the incident side.
