Piezoelectric acceleration sensor
A piezoelectric acceleration sensor comprises a piezoelectric element, a metallic sheet and a circuit board. The piezoelectric element is polarized in a predetermined direction. The circuit board includes a circuit portion and a roughly flat shaped base portion. The base portion protrudes from an end portion of the circuit portion. One of surfaces of the metallic sheet is fixed to and supported by a surface of the base portion. The piezoelectric element is fixed to and supported by a remaining one of the surfaces of the metallic sheet in a manner that the piezoelectric element and the base portion do not overlap each other in the predetermined direction.
