摘要：
A second housing (12) whose center portion (12a) is depressed and whose end portion (12b) around the center portion (12a) is formed like a visor is arranged around a first housing (11) whose center portion (11a) is depressed and whose end portion (11b) around the center portion (11a) is formed like a visor, and a hollow portion (14) is formed between the first housing (11) and the second housing (12) by sandwiching a packing (13) between the end portions (11b,12b) of the housings (11,12). Further, degassed water (15) for preventing empty heating is filled in the hollow portion (14), and an ultrasonic transducer (16) is placed on the surface of the center portion (11a) of the first housing (11). A weight (17) for preventing the vibration of the wall (12c) is provided on the wall surface of the second housing (12). Since the vibration of the wall (12c) of the housing (12) is suppressed by the weight (17), vibration energy returns toward the bottom surface of the center of the housing (12) through water and is radiated from the bottom surface efficiently as ultrasonic waves.
