MICRO-PASSAGE CHIP

摘要

Means for overcoming the problems which the conventional glass microchannel chips have are disclosed. That is, a microchannel chip in which microchannels can be formed at a low cost, and which has a high chemical resistance is disclosed. The microchannel chip is constituted by a substrate made of carbon, which has a channel in its surface; and a cover composed of a glass plate bonded to the substrate. The cover is bonded to the substrate by heating at least a part of the contact surface at which the substrate is in contact with the cover.
