ABSTRACT:
A fluid chip has a liquid support25for supporting a liquid24, a fluid passage22formed by being surrounded by the liquid support25and through which the liquid24moves, and a plurality of magnetic particles21disposed in the fluid passage24. The magnetic particles21are aggregated by a permanent magnet23so as to block the fluid passage22and thus cut off flow of the liquid24. The magnetic particles21are dispersed along a part of a wall of the fluid passage22so as to open the fluid passage22and thus allow the liquid24to flow.
