A vibration detector comprising: an impedance element located on the piezoelectric element side; and a connection portion between the impedance element and the electrode terminal is covered with an electrical insulator.

Claims

[Scope of utility model registration request]

A cylindrical base member with a bottom that is attached to the object to be measured, a weight that is fixed within the base member and receives vibrations from the object to be measured, a base member that is disposed between the weight and the base member, and A piezoelectric element that electrically converts the acting force applied from the weight, an electrode terminal having an L-shaped cross section that is connected to the electrode on the side opposite to the base member of the piezoelectric element and detects its output, and a piezoelectric element that is connected to the electrode terminal and that is connected to the weight. 1. A vibration detector comprising: an impedance element located on a side opposite to the piezoelectric element; and a connection portion between the impedance element and the electrode terminal is covered with an electrical insulator.
