1. An axial-flow particle sensor comprising:

  • a sensor element comprising a vibrating portion having a sufficient mass for responding to the collision of a solid particle in a fluid and a converter for detecting the vibration of said vibrating portion and converting the vibration to electric signals;

    a housing for fixing said sensor element;

    an inlet of fluid; and

    an outlet of fluid;

    wherein said outlet is located in the opposite side of said inlet relative to said sensor element, a throughhole is opened in at least a part of the circumference of said vibrating portion, and said vibrating portion of said sensor element is located at the extension of fluid flow formed at said inlet so that the fluid entering from said inlet flows through said throughhole and flows out from said outlet.
