PURPOSE: To provide a transmitter-receiver for sonar which secures the waterproof property of a lead-out part and shortens the intervals of transmitter- receivers by bending a cable like an L to arrange it along the edge part of a case and leading it out from the case. CONSTITUTION: A cable 52 electrically connected to an acoustic element 51 is bent like an L, and a cable 52a on the bending side is arranged along an edge part 1a of a case 1 and is led out from the left end of a lower side 1b of the case 1, and the edge part 1a of the case 1 along which the cable 52a is arranged is formed so as to project from the other edge part 1c. A cable 52F of a transmitter-receiver 1F in the upper right is led out from between the projecting part (edge part) 1a of a transmitter-receiver 1H in the lower right and a side part 1d of a transmitter-receiver 1G in the lower left. Since a space S is formed between the other edge part 1c of the transmitter-receiver 1H and the side part 1d of the transmitter-receiver 1G, the cable 52F is not excessively bent. Intervals A of transmitter-receivers 1E and 1F and transmitter- receivers 1G and 1H are shortened to about 3-fold diameter D of the cable 52F.
