Abstract
In an exemplary embodiment, a vibration waveform sensor includes a pair of conductive pads, and a piezoelectric elementwhose terminal electrodes are connected thereto, which are provided on a board, and these are surrounded by a conductive ring-like spacer. On the interior side of the spacer, a cover partsubstantially like a disk is provided in a manner covering over the pair of conductive padsand the piezoelectric element. The cover partcuts off any humming noise from the top face of the piezoelectric elementover a continuous surface, which results in a reduction of humming noise.
