An ultrasonic wave concentration meter is provided to reduce an error range by forming more than one pair of transmission/reception vibrators, and calculating an average value after measuring fluid concentration at positions different from each other. An ultrasonic wave concentration meter comprises a fluid pipe(10), a measurement pipe(220) and a transmission unit(30). The fluid pipe forms a flange(11) on an end for measuring concentration. The measurement pipe has short tube shape, and forms a flange(21) coupled by a linkage method using bolts and nuts and having the same diameter the fluid pipe on both ends. The transmission unit is inserted into an insertion hole of the measurement pipe, fixed in a fixing table so that a transmission vibrator(31) and a reception vibrator exposed to internal space of the measurement pipe are faced each other, and provided with a calculation amplifier(34) calculating a measurement value of the transmission/reception vibrators.
