Connecting structure of a liquid sending apparatus, fuel-cell type electricity generating apparatus, and electronic device

A connecting structure of a liquid sending apparatus, comprising:

• an electroosmotic flow pump having a first electrode upstream of an electroosmosis material and a second electrode downstream of the electroosmosis material, and
• a flow-path structure which defines flow-paths for liquid upstream and downstream of the electroosmotic flow pump, which is provided downstream of the electroosmotic flow pump with a ventilation hole communicating with inside and outside of the flow-path, and which is provided with a hydrophobic film which covers the ventilation hole and is permeable to bubbles, wherein
• the hydrophobic film is annularly provided in the flow-path downstream of the electroosmotic flow pump, and a hydrophilic film which is permeable to liquid is provided on a central portion of the same plane as the hydrophobic film.
