PROBLEM TO BE SOLVED: To provide a low-priced acceleration sensor that enables to detect acceleration of an axis line, which is a measuring object, and the acceleration of other line with reproducibility. SOLUTION: A supporting means 2 with an installation face 2f that is orthogonalized to a virtual acceleration plane extending in parallel with a direction where acceleration of a z-axis becoming a measurement object occurs is used. A fixed end part 3a of a piezoelectric ceramic element 1 is fixed to the supporting means 2 so that a part becoming a fulcrum 3c of the piezoelectric ceramic element 1, is set in non-parallel with the installation face 2f. Also, the fixed end part 3a of a piezoelectric ceramic element 1 is fixed to the supporting means 2 so that a surface part (a surface part of a variation part 3b), which extends between the part becoming the fulcrum 3c of the piezoelectric ceramic element 1 and a free end part 3d, passes the part becoming the fulcrum 3C to intersect a virtual plane 1 extending in parallel with the installation face 2f. Therein, an intersection angle θ1 and θ2 are set in a range of 0-45 degree. |
