We have found a similarity between the size spectra of the observed interplanetary dust and the survived cometary dust, referring to the dynamical behaviour of the dust leaving the comet. As a result, we can suggest that short-period comets with relatively higher eccentricities are major source of the interplanetary dust, especially those with radii less than 10 µm. It is predicted, furthermore, that a supply rate of the dust, which move on bound orbits after leaving the comet, becomes about 8×10 g/s from 85 short-period comets, and nearly 3×104 g/s from 101 long-period comets.
