Abstract: A physical quantity sensor includes a sensor portion, a casing, and a vibration isolator. The casing includes a supporting portion with a supporting surface that is located to face an end surface of the sensor portion. The vibration isolator is located between the end surface of the sensor portion and the supporting surface of the casing to join the sensor portion to the casing. The vibration isolator reduces a relative vibration between the sensor portion and the casing.

Abstract: An ultrasonic sensor includes: an ultrasonic element provided to transmit or receive an ultrasonic wave propagating along a directional axis; and an element housing case that includes a case diaphragm having a thickness direction along the directional axis. A resonant space is defined between the case diaphragm and the ultrasonic element for the propagating wave, by housing the ultrasonic element while separating the ultrasonic element from the case diaphragm. A horn shape is defined in the element housing case in which a width of the resonant space in a direction orthogonal to the directional axis is reduced as the resonant space extends in an axial direction parallel to the directional axis.

Abstract: An ultrasonic sensor includes: an element storage case including a case-side diaphragm having a thickness direction along a directional axis; and an ultrasonic element accommodated in the element storage case and spaced apart from the case-side diaphragm. The ultrasonic element includes an element-side diaphragm having the thickness direction along the directional axis and provided by a thin part of a semiconductor substrate. The semiconductor substrate is arranged to provide a closed space between the case-side diaphragm and the element-side diaphragm. The semiconductor substrate is fixed and supported by the element-storage case.
