PROBLEM TO BE SOLVED: To provide a trace liquid dilution method that uses a microfluid device, capable of easily providing microfluid having various dilution ratios. SOLUTION: This trace liquid diluting method has processes of weighing a first microfluid and a second microfluid into first and second weighing units 11d and 13d of a first mixing unit 11; mixing the first microfluid and the second microfluid as a diluent; discharging a first specimen diluent, weighing at least part of first mixed microfluid into the first or second weighing unit of a second mixing unit 21; weighing the second or first microfluid into the second or first weighing unit of the second mixing unit; mixing the first specimen diluent and the diluent, obtaining a second specimen diluent, and discharging it from a discharge unit. Mixing units in n-2 (n is 3 or larger natural number) are connected to the back stage of the first and second mixing units, each specimen diluent is discharged from the discharge unit of each mixing unit, and a specimen diluent of different concentration is obtained.
