Title: OPTICAL COMMUNICATION MODULE
Abstract:
Provided is an optical communication module (1), wherein optical elements (20, 21) are disposed on a main surface (30A) of a substrate (30). A transparent resin block (10) is disposed on the main surface (30A) of the substrate (30), and seals the optical elements (20, 21). The resin block (10) includes hole sections (11, 12) that are recessed toward the substrate (30) from the upper surface (10A) of the block. At least a portion of the bottom surfaces of the hole sections (11, 12) form lens surfaces (13, 14) which project in a direction opposing the substrate (30). A transparent lid section (5) is connected to the upper surface (10A) of the resin block (10) and covers the hole sections (11, 12). Hollow passages (44, 45) are provided in the resin block (10), and communicate an inner space and an outer space, the inner space being enclosed by the hole sections (11, 12) and the lid section (5).
