A flow-rate measurement device which measures a flow rate of a fluid flowing through a fluid flow channel unit includes a tubular measurement flow channel unit that is stored in the fluid flow channel unit and has an inside in communication with the fluid flow channel unit. The flow-rate measurement device also includes a pair of sealing materials that blocks a flow of a fluid and is provided to encircle outer peripheries of the measurement flow channel unit at a first end and a second end; and a measurement unit including a substrate, on which a measurement circuit is mounted, and a pair of ultrasonic transducers. Further, the pair of ultrasonic transducers is electrically and fixedly connected to the substrate in the measurement unit, and the measurement unit is disposed between the pair of sealing materials on the measurement flow channel unit.
