Abstract
An ultrasonic sensor includes: a floored cylindrical case, a piezoelectric vibration element and input-output terminals. The floored cylindrical case has a separately prepared cylinder part and a separately prepared vibration part, and the cylinder part and the vibration part are adhered together with an adhesive material having an elastic modulus in the range from 100 through 20,000 kgf/mm.sup.2 at a temperature range from 25 through 125.degree. C. The piezoelectric vibration element is disposed on the inner bottom floor of the floored cylindrical case. The input-output terminals are electrically connected to the piezoelectric vibration element and are adapted for electrical connection to outside of the floored cylindrical case.
