<p>Provided is a novel micro passage chip having a structure capable of tran sferring a fluid from above the substrate of the micro passage chip even if physical or mechanical drawing means is not used. The micro passage chip is characterized to include at least a first substrate and a second substrate, and an intermediate substrate interposed between the first substrate and the second substrate. At least one of the adhered faces of the first substrate and the intermediate substrate has a first unadhered thin film layer formed thereon. At an arbitrary position over the first unadhered thin film layer, there is arranged at least one fluid port, which contacts with the first una dhered thin film layer and which is opened to the outer surface of the first substrate. On the face on at least one of the adhered faces of the first su bstrate and the intermediate substrate, there is so formed at least a portio n of the second unadhered thin film layer, which has a length equal to or di fferent from that of the first unadhered thin film layer, as vertically over laps the first unadhered thin film layer through the intermediate substrate. On at least one portion over the second unadhered thin film layer, there is arranged a pressure port, which contacts with the second unadhered thin lay er and which is opened in the outer surface ofthe first or second substrate.</p> |
