PROBLEM TO BE SOLVED: To provide a receiving device having a simple configuration to be used in an environment where multi-pass occurs.SOLUTION: A receiving device includes: a receiving part (10) configured to receive a radio wave from outside; and reflection parts (11, 12) having reflection surfaces 11a, 12a with a plurality of reflection directions and configured to reflect the radio wave to the receiving part. An optical distance (d1) between one reflection surface 11a and the receiving part (10) is different from an optical distance (d2) between the other reflection surface 12a and the receiving part (10). |
