PROBLEM TO BE SOLVED: To provide a microanalysis chip which can detect particulates in a specimen liquid, and which efficiently eliminates particulates other than an inspection object from the specimen liquid dropped in a reservoir.SOLUTION: A microanalysis chip which can detect particulates in a specimen liquid, includes: a base plate 10; a flow channel 20 provided in a manner to allow the specimen liquid to flow in the main face side of the base plate 10; a circular bank 14 provided on the main face of the base plate 10; a liquid introduction port 40 provided on the main face of the base plate 10 inside the bank 14 so as to be connected to one end of the flow channel 20; a reservoir 30 capable of storing the specimen liquid; and a filter 50 which is provided between the liquid introduction port 40 and the one end of the flow channel 20 and which includes first micropores 13 for allowing the particulates in the specimen liquid to pass through.SELECTED DRAWING: Figure 1 |
