The optical fiber supporting member includes a beam part having (i) a first main surface on which the bonding pad is provided and (ii) a second main surface opposite to the first main surface, and a pillar part which is fixed to a base and is joined to the beam part on an end portion of the beam part such that the second main surface and the base face each other while being spatially away from each other. | 2013-01-24 |
