Abstract
A microchip for forming an emulsion has a first glass substrate, a second glass substrate and a silicon substrate. The silicon substrate has formed therein a first fluid flow path through which a first fluid flows and a second fluid flow path through which a second fluid that is not mixed with the first fluid flows. The first fluid flow path has a plurality of branched flow paths that join at a joint portion. The second fluid flow path communicates with the joint portion. The silicon substrate has formed therein an emulsion formation flow path that faces an edge portion of the second fluid flow path at the joint portion. An emulsion composed of the first fluid and the second fluid that is surrounded by the first fluid is formed in the emulsion formation flow path.
