An optical module includes a board; a photoelectric transducer disposed on the board; an optical waveguide that is connected to the board and transmits light entering or emitted from the photoelectric transducer; an optical connector including a first end connected to the optical waveguide and a second end to be connected to an optical cable; a housing that houses the board, the photoelectric transducer, the optical waveguide, and the optical connector; and a conductive part that is provided between the optical waveguide and the housing, in contact with the housing, and formed of an elastic conductive material or a radio absorbing material.
