MICROCHANNEL DEVICE

WIPO Patent Application WO/2023/210332

A1

The present invention provides a microchannel device which is thin and which enables stable measurement. Provided is a microchannel device that uses a porous base material, said microchannel device having a channel region which uses porousness and having, in a part of the channel region, a region A in which a component having ion selectivity exists in pores of the porous base material. In the region A, the component having ion selectivity exists in pores on one surface X side of the porous base material, and the other surface Y side is a channel in which a void exists. A working electrode is provided to the surface on the surface X side in the region A such that at least part of the working electrode overlaps with the component having ion selectivity. A reference electrode is provided to a region B excluding the region A of the channel region. The region A and the region B are formed on the same porous base material.
