Summary:PROBLEM TO BE SOLVED: To obtain a piezoelectric triaxial acceleration sensor which does not require the adjustment of the level fluctuations of X-, Y-, and Z-axis acceleration signals by means of a signal processing circuit. SOLUTION: Portions L1a and L2a positioned on the stress generating area 8C of X-axis connecting lines L1 and L2 are arranged so that the portions L1a and L2a may be positioned on an X-direction virtual line XL, and, portions L4a and L4b positioned on the stress generating area 8C of a Y-axis connecting line L4 are arranged so that the portions L4a and L4b may be positioned on a Y-direction virtual line YL. In addition, portions L5a, L5b, L5c, and L5d positioned on the stress generating area 8C of a Z-axis connecting line L5 are arranged so that the portions L5a, L5b, L5c, and L5d may be positioned on two virtual lines which become axially symmetric to each other about the virtual line XL or YL.
