Abstract
An optical receiver module includes a light receiving element that has a first electrode and a second electrode for receiving a bias and converts an optical signal inputted into an electrical signal to output the electrical signal via the first electrode. A signal line extends from the first electrode through the light receiving element-side signal pad and the second wire to the amplifier-side signal pad. A bias line extends from the second electrode through the light receiving element-side bias pad, the first wire, and the third wire to the first and second amplifier-side bias pads. The signal line three-dimensionally intersects with the bias line at an interval in a direction of the loop height of the first wire and that of the second wire.
