Summary:Provided are a channel member and an ultrasonic fluid-measuring apparatus that can prevent the disturbance from occurring in the ultrasonic waves due to disturbance of a fluid. A channel member (15) includes a first side wall part (21) and a second side wall part (22) that are parallel to each other, a first ultrasonic wave input/output section (32) and a second ultrasonic wave input/output section (33) provided in the first side wall part, a reflecting surface (35) provided on an inner surface of the second side wall part, and an ultrasonic wave transmission membrane (38) that covers the first ultrasonic wave input/output section and the second ultrasonic wave input/output section and transmits ultrasonic waves (36, 37) therethrough. The first ultrasonic wave input/output section and the second ultrasonic wave input/output section are continuous with each other, and the ultrasonic wave transmission membrane covers both the first ultrasonic wave input/output section and the second ultrasonic wave input/output section together.
