Abstract
Relates to an interdental cleaning tool provided on the peripheral surface of a shaft member 1 with one or a plurality of projections 2, the projections being pinnulate elements or cirrate elements, and shaft member 1 and projections 2 being integrally molded from synthetic resin, whereby there may be afforded a soft touch against the tissues of the oral cavity during use, deviation in extraction force of the pinnulate members and cirrate members may be prevented, and production costs may be reduced.
