PROBLEM TO BE SOLVED: To provide a highly reliably optical unit capable of easily and accurately controlling a region to which a packing material is applied, and forming a void between an optical component and a base material in a desired state to surely secure both low light loss and electrode joint reliability, and a method for manufacturing the optical unit.SOLUTION: An optical unit in which an optical component 10 having an optical element 12 is loaded on a base material 20 having an optical waveguide 21 includes: a first hydrophobic region 14 formed in a site including the optical axis of the optical component 10; a second hydrophobic region 24 formed in a site facing the first region 14 on the surface of the base material 20; and a hydrophilic packing material 4 for packing the periphery of the first region 14 and the second region 24 between the optical component 10 and the base material 20. |
