Provided is a simple and compact microchemical chip which has a fine flow path reliably formed therein through which a valuable specimen originated from a biological object or a trace amount of a dilute reagent is made to flow; does not break even when a fluid sample is made to flow through pressurization; makes it possible to flow the fluid sample to the flow path accurately, reliably, and as desired; makes it possible to accurately, simply, and quickly analyze a useful substance such as a biological component of the specimen and cause the useful substance to react; and can be produced with a high yield, on a large scale, and so as to be homogeneous. A microchemical chip 1 comprises: a rubber sheet 20 having a penetrated flow path 26 which chemically reacts a pressurized fluid sample selected from a specimen and a reagent by flowing thereinto; substrate sheets 10,30 which sandwich the rubber sheet 20 and bond to both faces thereof by direct bond or by chemical bond through a silane-coupling agent and are selected from the group consisting of metal, ceramics, glass, and resin; and a hole for injecting the fluid sample 11a, 11b into the flow path and a hole for draining the fluid sample flowed therefrom 12a, 12b, 12c which are opened into the substrate sheet 10. |
