An ultrasonic flow rate measurement device includes a measurement channel, through which a fluid to be measured flows; and a sensor fixing casing (7) having openings formed in the measurement channel and sensor fixing cavities (10, 11) communicating with the openings. Moreover, the ultrasonic flow rate measurement device includes a pair of ultrasonic sensors contained in the sensor fixing cavities (10, 11), for measuring the flow rate of the fluid to be measured; and a flow rate measuring unit for detecting the flow rate based on an ultrasonic wave propagation time between the pair of ultrasonic sensors. Furthermore, the ultrasonic flow rate measurement device includes a suppressing member (20) formed at each of the openings, for suppressing the fluid to be measured from intruding into each of the sensor fixing cavities (10, 11), wherein the suppressing member (20) is molded integrally with the sensor fixing casing (7). |
