This gas measurement device is provided with an inflow opening through which a fluid flows in and an outflow opening through which the fluid flows out, and determines the flow rate of the fluid flowing from the inflow opening through the outflow opening. The gas measurement device is provided with a plurality of measurement flow paths disposed in parallel between the inflow opening and the outflow opening, flow-rate measurement units (61a-61e) disposed in the plurality of measurement flow paths and for determining the flow rate of the fluid passing through these measurement flow paths, an average flow-rate computation unit (92) for determining the average value of the flow rates determined by the flow-rate measurement units (61a-61e), and a flow-rate comparison unit (93) for acquiring index values representing the relationships between the average value determined by the average flow-rate computation unit (92) and the flow rates determined by the flow-rate measurement units (61a-61e) and determining whether these index values reach at least a prescribed value. As a result of this configuration, the present invention makes it possible to assess individual flow rates for erroneous measurement results solely on the basis of the results of the individual measurements taken in the measurement flow paths.
