  • Ultrasonic sensor
    Patent number: 11486758
    Abstract: An ultrasonic sensor includes a casing and a piezoelectric vibrator element. The casing includes a first unit made of a metal and a second unit made of a resin. The first unit has a cylindrical or substantially cylindrical shape extending in a first direction. The second unit is connected to one end of the first unit in the first direction and includes a cylindrical section and a bottom plate. The cylindrical section extends in the first direction. The bottom plate is a disk-shaped portion which closes an end of the cylindrical section positioned farther away from the first unit in the first direction. The piezoelectric vibrator element is mounted on the bottom plate.
