It is a chip provided with an internal space that can be used as a flow path inside, and provides a micro flow path chip having excellent drug non-absorption of the flow path. An internal space S connecting the plurality of openings H1 and H2 and the plurality of openings H1 and H2 is formed, and at least a part of the surface in contact with the internal space S is CF 2 = CFX (X is a fluorine atom, a chlorine atom, Alternatively, a microchannel chip made of a fluorine-containing copolymer containing 5 to 99 mol% of units based on CF 3 ). |
