Beschreibung
Zusammenfassung:	Provided is an electrochemical sensor device capable of micromachining a channel while maintaining its measurement sensitivity and of reliably quantitating an analyte in a trace amount of a sample. An electrochemical sensor device includes: a channel portion formed in a substrate; and working electrodes for subjecting an analyte in a solution flowing in the channel portion to electrochemical measurement, the electrochemical sensor device includes a plurality of measuring portions individually provided with the working electrodes, and each of the working electrodes has a plurality of conductive protrusion portions formed to protrude from a bottom surface of each of the measuring portions.
