Abstract
An ultrasonic transmitting and receiving apparatus includes a casing, a vibration isolating member, and a piezoelectric element. The casing has a bottom, an inner peripheral wall, and an outer peripheral wall, and these components are integral and define a monolithic structure. The inner peripheral wall and the bottom define a first recess. The outer peripheral wall, the inner peripheral wall, and the bottom define a second recess. The second recess is filled with the vibration isolating member. The piezoelectric element is fixed on the bottom facing the first recess in the casing.
