PROBLEM TO BE SOLVED: To examine in detail the aggregation state of blood platelets by while the device is low in lost. SOLUTION: Buffer solution D<SB>1</SB>and blood D<SB>2</SB>are allowed to flow in the layered state in a passage B<SB>3</SB>of a microchemical chip. An aggregate agent G for aggregating platelets in the blood is applied the wall surface on the side, whereupon the buffer solution D<SB>1</SB>flows. If the flow rate of the blood D<SB>2</SB>is heightened in this state, the laminar flow width W<SB>2</SB>of the blood can be widened, and the reaction between the aggregating agent G and the platelets can be analyzed in detail. Even when images or dynamic images are required to be taken, in order to compare the non-aggregation state with the aggregation state, by only photographing "a spot where the aggregating agent is applied (namely, a reaction part G)" is sufficient, and arrangement of two cameras or installation of a moving mechanism of the camera or the microchemical chip is not required to be installed, and the cost of the device can be reduced by this amount.
