1. A channel device comprising:
a first channel member having a first channel;
a second channel member having a second channel;
a porous membrane provided between the first channel member and the second channel member to cover and separate between the first channel and the second channel;
a first transparent electrode provided in contact with the first channel and facing the porous membrane; and
a second transparent electrode provided in contact with the second channel and facing the porous membrane,
wherein the first channel is formed between the first channel member and the porous membrane,
wherein the second channel is formed between the second transparent electrode, the second channel member and the porous membrane,
wherein at least one of the first transparent electrode and the second transparent electrode is a planar electrode,
wherein the planar electrode is an electrode having an area larger than an entire area between the first channel and the second channel in a region where the first channel and the second channel are separated from each other by the porous membrane, and
wherein the second channel member is a plate member having a through-hole that serves as the second channel, a holding plate that abuts on the second channel member and closes the through-hole that serves as the second channel is further provided, and the second transparent electrode is formed on an entire surface of the holding plate that abuts on the second channel member.
