ACCELERATION SENSOR

摘要

PROBLEM TO BE SOLVED: To provide an acceleration sensor that can reduce or prevent degradation in the detection accuracy and reduce, or prevent occurrence of interference with surrounding parts or the like. SOLUTION: The x axis is set in the height method of cross sections of the first and second cantilever sections 2 and 3, x=0 is set at the upper ends of the cross sections of the cantilever sections 2 and 3; x=h is set at the lower ends of the cross sections of the cantilever sections 2 and 3, and the widths of the cross sections of the cantilever sections 2 and 3 are set to be W(x). At this time, the sectional shapes of the cantilever sections 2 and 3 are set so that W(x)≤W(0) or W (x)≤W(h) are established in the range of 0
