 A quantification unit that quantifies a sample by volume, a main channel that communicates with the quantification unit, a measurement unit that measures a quantified sample formed in the main channel, and a sample that communicates with the main channel and transfers the sample from the quantification unit to the measurement unit And a pressure introduction port for introducing pressure into the main flow path, and the measurement unit has an electrical property measurement unit for measuring the electrical property of the sample, and an optical property for measuring the optical property of the sample. A measurement unit comprising at least one of the measurement unit. The measurement unit according to claim 1, further comprising a sample receiving unit that receives a sample to be quantified and communicates with the quantification unit. The measurement unit according to claim 2, wherein the sample receiving portion is formed so that a capillary blood collection tube can be inserted. The measurement unit according to claim 1, wherein the electrical characteristic measurement unit includes a partition plate installed so as to close the flow channel and having pores, and two electrodes exposed to the flow channel across the partition plate. The measurement unit according to claim 1, wherein the optical characteristic measurement unit is provided in a part of the main channel, and the part is transparent and has a shape that can be sandwiched between the light source and the light receiving element. The measurement unit according to claim 1, further comprising an upper plate and a lower plate that overlap each other, wherein at least one of the upper plate and the lower plate is formed with a quantitative portion, a main flow path, and a measurement portion. The measurement unit according to claim 1, wherein the main flow path includes a blocking unit that blocks bubbles from moving in the direction of the quantitative unit. The measurement unit according to claim 1, wherein the main channel includes a rectifying unit that rectifies the diluted sample to be transferred.
