Claim 0:
1. A fluid handling device, comprising:
a substrate including a sample-channel groove, a dispersion-medium-channel groove, a dispersion-liquid-generation-part recess, and a dispersion-liquid-channel groove;
a film that covers the substrate;
a sample channel for allowing a sample to flow therethrough, the sample channel being a region surrounded by the sample-channel groove and the film;
a dispersion medium channel for allowing a dispersion medium to flow therethrough, the dispersion medium channel being a region surrounded by the dispersion-medium-channel groove and the film;
a dispersion liquid generation part connected to the sample channel and the dispersion medium channel, and configured to divide the sample by the dispersion medium to generate a dispersion liquid in which a liquid droplet of the sample is dispersed in the dispersion medium, the dispersion liquid generation part being a region surrounded by the dispersion-liquid-generation-part recess and the film; and
a dispersion liquid channel connected to the dispersion liquid generation part, and configured to allow the dispersion liquid to flow therethrough, the dispersion liquid channel being a region surrounded by the dispersion-liquid-channel groove and the film, wherein
Y≤0.0436X−1.2563 is satisfied, where X denotes a contact angle [° ] between a portion of an inner wall of the dispersion liquid channel and water, and Y denotes a viscosity [mPa·s] of the sample measured at 25° C. by a falling-ball viscometer.
