Abstract

A microchip is provided, which includes a substrate including a fluid channel structure. The fluid channel structure includes a first fluid introduction channel and a second fluid introduction channel configured to meet so as to allow merging of a first fluid introduced from the first fluid introduction channel and a second fluid introduced from the second fluid introduction channel. A tapered portion is configured to be positioned after merging the first fluid and the second fluid so as to suppress a spiral flow field generated after the merging.
