To provide a simple and convenient manufacturing method of a silicone coating fabric base for an airbag which is excellent in blocking resistance property and is excellent in internal pressure holding property when manufacturing the airbag such as a curtain airbag.SOLUTION: The manufacturing method of the silicone coating fabric base for the airbag having a silicone rubber layer on at least one surface of the fabric base for the airbag, includes: a first process which coats a liquid-like silicone rubber composition whose viscosity of 25°C is 5,000-300,000 mPa*s so that coating weight is 80-300 g/mon at least one surface of the fabric base for the airbag; a second process which decreases the coating weight of the coated liquid-like silicone rubber composition to 10-60 g/m; and a third process which hardens the liquid-like silicone rubber composition after decrease in weight.SELECTED DRAWING: None
