Vibration detector

A vibration detector comprising:

• a detection element having a structure in which an insulation base material is formed with first and second via holes penetrating therethrough in a thickness direction, first and second inter-layer connection members formed of different metals are embedded in the first and second via holes, and the first and second inter-layer connection members are connected in series alternately;
• a heat generation member disposed on one surface of the detection element;
• and
• a protection member disposed on the other surface of the detection element;
• wherein
• at least one of the metals forming the first and second inter-layer connection members is a sintered alloy sintered in a state in which metal atoms maintain a crystal structure thereof,
• the heat generation member generates heat when subjected to at least one of deformation and friction by a vibration from the outside,
• the detection element detects a heat flux between the heat generation member and the protection member by an electromotive force occurring in the first and second inter-layer connection members which are series-connected alternately, and
• the vibration detector further comprises a detection processing means which performs a detection process of data regarding vibration based on the electromotive force occurring in the detection element.
