Abstract:
1. A film light guide package formed by a supporting portion for supporting an optical element for emitting or receiving an optical signal, and a lid for covering the supporting portion; wherein the supporting portion includes a supporting surface for supporting at least one end of a film light guide including an incident/exit port of the optical signal in the film light guide for optically coupling with the optical element and transmitting the optical signal; and wherein a first direction is a perpendicular direction with respect to the supporting surface of the supporting portion, a length in the first direction from the supporting surface of the supporting portion to the lid is longer than a length in the first direction in a region of the film light guide supported by the supporting surface of the supporting portion, or wherein the lid includes a supporting surface for supporting at least one end of the film light guide including an incident/exit port of the optical signal in the film light guide for optically coupling with the optical element and transmitting the optical signal; and wherein the first direction is a perpendicular direction with respect to the supporting surface of the lid, a length in the first direction from the supporting surface of the lid to the supporting portion facing the supporting surface of the lid is longer than the length in the first direction in the region of the film light guide supported by the supporting surface of the lid, wherein an adhesive having higher flexibility than the film light guide is filled in a region of at least one part of a spatial region formed between the film light guide and the supporting portion or between the film light guide and the lid.
