Fluid handling device

A fluid handling device, comprising:

• a substrate and a film adhered to one surface of the substrate, wherein the substrate includes
• a sample channel groove for forming a sample channel along with the film, the sample channel being for allowing a sample to flow,
• a dispersion medium channel groove for forming a dispersion medium channel along with the film, the dispersion medium channel being for allowing a dispersion medium to flow,
• a dispersion liquid generation recess for forming a dispersion liquid generation part along with the film, the dispersion liquid generation part being connected to the sample channel and the dispersion medium channel, the dispersion liquid generation part being for generating a dispersion liquid containing a droplet of the sample dispersed in the dispersion medium by dividing the sample by the dispersion medium, and
• a dispersion liquid channel groove for forming a dispersion liquid channel along with the film, the dispersion liquid channel being connected to the dispersion liquid generation part, the dispersion liquid channel being for allowing the dispersion liquid to flow, and wherein
• the film contains an adhesive coated with a coating material in parts of the film, the parts facing the sample channel groove, the dispersion medium channel groove, the dispersion liquid generation recess, and the dispersion liquid channel groove.
