Abstract
A pressure sensor includes a sensor chip and a resin portion. The sensor chip extends in a lengthwise direction and includes a membrane whose length in a thickness direction perpendicular to the lengthwise direction is smaller than another part, and a piezoelectric element provided in the membrane. The sensor chip includes a fixed end that is covered with and fixed to the resin portion, and a free end opposite from the fixed end in the lengthwise direction. The free end is spaced away from the resin portion in the lengthwise direction, and the membrane is located in the free end. A shortest separation distance between the membrane and a part of the resin portion covering the sensor chip is equal to or larger than a length of the sensor chip along a crosswise direction of the sensor chip perpendicular to both the lengthwise direction and the thickness direction.
