The invention provides a damping component used for reducing the interference of external vibration on a crystal oscillation element. The damping component comprises a base, at least three groups of damping elements installed on the base and used for buffering external vibration, and a supporting element comprising a concave portion and at least three ends, wherein the concave portion is used for supporting the crystal oscillation element, the ends are installed at predetermined positions of the damping elements, and each damping element comprises two damping bodies made of an elastic material and arranged at the upper side and lower side of the ends of the supporting element respectively, and a pressing part which penetrates through the damping bodies and the ends of the supporting element to be connected with the base and is used for pressing the damping bodies to enable the damping bodies to be pressed into a low-rigidness area. In this way, the damping component is simple in structure, light, convenient to install, adjustable in rigidness and damping performance, high in omnidirectional damping performance, high in durability, resistant to high temperature, low temperature and corrosion, not prone to aging, highly practically and broad in application prospect.
