ABSTRACT:
In a vibration sensor including a base member shaped in the form of a sleeve having a structure for installation on an object of measurement, a piezoelectric conversion portion put onto the periphery of the same, and lead wire member connecting the same with the outside of the sensor, the present invention is characterized in that the piezoelectric conversion portion and a portion of the lead wire member are integrally covered with polyamide resin and it is thereby formed into a case member. The present invention with the above described arrangement makes most of the characteristics of the polyamide resin having a strong crystalline polymer structure, whereby the frequency response characteristic of the vibration sensor is improved against thermal stress.
