Abstract: An optical receiver module includes: a lens array including a plurality of condenser lenses arranged in one direction to define a plane with optical axes in parallel to each other; and a light receiving element array including a plurality of light receiving elements each configured to receive light emitted from each of the condenser lenses. The light receiving element array includes: a semiconductor substrate to which the light from each of the condenser lenses is input and through which the light is transmitted; and light receiving portions each configured to receive the light transmitted through the semiconductor substrate and convert the light into an electrical signal. A shift of the optical axis of each of the condenser lenses from a center of each corresponding one of the light receiving portions is larger in a direction perpendicular to the one direction within the plane than in the one direction.

Abstract: A base material includes a pair of end regions located on both sides in a first direction, and an intermediate region located between the pair of end regions. The intermediate region includes a pair of side edges on both sides in a second direction orthogonal to the first direction. Both the pair of side edges do not project outward in the second direction from the pair of end regions. At least one of the pair of side edges has a shape recessed inward in the second direction from the pair of end regions. Terminals include end pads and a side pad. The end pads are located in each of the pair of end regions of the base material and arranged in the second direction. The side pad is located at at least one of the pair of side edges of the base material.
