The use of a granular material which is for orally fast disintegrating tablets and comprises starch and tannic acid allows provision of tablets that can be produced by a simple process with general-purpose production equipment, disintegrate fast and absorbs water in the mouth, and have a proper level of shape retainability for practical use. The present invention also provides a method for producing an orally fast disintegrating tablet, the method comprising compression molding of a granular material for orally fast disintegrating tablets comprising starch and tannic acid, or a mixture of the granular material for orally fast disintegrating tablets and other ingredients (an additive, an active ingredient, and/or the like).
