A fluid processing apparatus including a 3D structure and a 3D structure, and a method for manufacturing the 3D structure, which enables control of fluid flow in a specific layer of a composite film for handling fluid. The 3D structure includes a composite film layer. The composite film layer includes a first photoresist layer 210 that does not include a hydrophobic agent and a second photoresist layer 214 that includes at least a hydrophobic agent, and the composite film layer includes the first photoresist layer and the second photoresist layer. Does not include an adhesion promoting layer. [Selection] Figure 8 |
