Title:
PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/249769
Kind Code:
A1
Abstract:
A pressure sensor according to the present invention is provided with a board, a first detecting element and a second detecting element which are mounted on an upper surface of the board and each of which includes a detecting unit for detecting pressure, and a resin package covering the first detecting element and the second detecting element. The resin package has a first exposing hole which exposes the detecting unit of the first detecting element upwards, and a second exposing hole exposing the detecting unit of the second detecting element upward. The resin package and the board have a rotationally symmetrical outer shape as seen from an orthogonal direction orthogonal to the upper surface of the board. When seen from the orthogonal direction, the first detecting element and the second detecting element are positioned with point symmetry with respect to a center point of the rotational symmetry of the resin package and the board.
