An object is to stably, continuously and easily detect reactions of filamentary biomolecules or polymers bridging between a pair of electrodes against reagents without employing any marker or labeling substances. A molecule detecting system for detecting a reaction of a molecule captured between electrodes to a reagent in a liquid, the system comprising: a detection device including a couple of electrodes and being capable of measuring a resonance frequency and an amplitude of the electrodes; a microfluidic deviceincluding a microfluidic channelwhich includes a channel openingon its one side, wherein an air-liquid interface the electrodes can pass through is formed in the channel opening; a pressure controlled microfluidic pumpconnected to an outletof the microfluidic channel; a movable holding device movably holding the detection device or the microfluidic device; and a controller controlling the detection device, the pressure controlled microfluidic pump, and the movable holding device.
