Abstract: The present invention provides an optical module capable of achieving downsizing and high densification, and reducing crosstalk as compared to a conventional optical module. An optical module includes: an optical device including multiple light receiving elements; a control device which transmits and receives signals to and from the optical device; and a substrate including multiple lines which allow passage of the signals. Anode terminals of the multiple light receiving elements are connected to different lines by first wires, respectively. Cathode terminals of the multiple light receiving elements are connected to different lines by second wires, respectively. Each first wire and the corresponding second wire cross each other and are disposed out of contact with each other. The wires connecting each light receiving element and the control device, namely, the wires of each channel cross each other.
