Provided is method of detecting presence or absence of a liquid suctioned by a syringe pump. The method includes, in a following order: a step of detecting a change in electrostatic capacitance between a pair of electrodes provided to a syringe, having a tubular shape in which a piston is moved in an axial direction of the syringe, of a syringe pump; and a step of detecting that liquid suction has been performed by the syringe pump based on the change in the electrostatic capacitance.
