1. A batch-molding multi optical transmission sheet assembly, comprising:
a batch-molding multi optical transmission sheet including
a sheet-like covering part made of plastic, and
a plurality of optical transmission regions, inside the sheet-like covering part, including a core region made of plastic that is disposed to extend along an extending direction of the sheet-like covering part and a clad region made of plastic that surrounds an outer circumference of the core region, the optical transmission regions being arranged in a line substantially parallel with each other along a principal surface of the sheet-like covering part;
a housing member including a disposition hole in which at least one end part of the batch-molding multi optical transmission sheet is housed;
a fixing means for fixing the batch-molding multi optical transmission sheet to the housing member; and
a lens array part that is disposed at an end face of the batch-molding multi optical transmission sheet, and includes a lens optically connected to each of a plurality of the core regions.
