It is desirable that the relative humidity of the gas for the fluidization of diamond particles is controlled to be 40% or higher. It is more desirable that ion bombardment onto the substrate surface to effect neutralization of the electrostatic charges. The fluidizing gas is humidified preferably by using a bubbling apparatus or spraying apparatus.
