An ultrasonic transmission/reception unit (50) includes a metal plate (16), an acoustic matching member (15), a piezoelectric substrate (17), a first lead wire (18a), a second lead wire (18b), and a vibration suppression member (11) containing a thermoplastic resin as a major component, the vibration suppression member being configured to cover, in a unitary manner, the other main surface (16b) of the metal plate (16), which is other than a portion of the other main surface to which the piezoelectric substrate (17) is fastened, a surface of the piezoelectric substrate (17), an end surface (16c) of the metal plate (16), an outer peripheral portion of the one main surface (16a) of the metal plate (16), the first lead wire (18a), and the second lead wire (18b). |
