In preparation of an emulsion by causing a mixture to flow from one syringe through a connector into another syringe, an object is to prevent the air from being entrained into cylinders and prepare the emulsion containing no air bubble, and another object is to easily prepare a homogeneous emulsion. Provided is a syringe pressing apparatus, including: a syringe fixing mechanism (20) for fixing two syringes (9) to a casing (10), the two syringes (9) being coupled to each other through a connector (99) a pressing mechanism (40) for alternately pressing syringe plungers (91) of the two syringes (9) and a plunger-pressure-measuring device for measuring a pressure with which the pressing mechanism (40) presses the syringe plungers (91).
