A synthetic resin needle of reinforced with combustible fibers whose longitudinal directions are arrayed straight or curvilinearly along the axial length of the needle. The reinforcing fibers may be dispersed uniformly in the synthetic resin of the needle, or in such a non-uniform manner that the concentration of the fibers in some portion around the peripheral wall of the needle is so scarce that the inner passage of the needle can be observed from outside.
