The present invention provides an oral film-form base having a rapid dissolution profile in the oral cavity and sufficient film strength, and having improved dosing properties by foaming in the oral cavity. An edible polymer that is soluble in water and an organic solvent having a solubility parameter of 9.7 or more, a foaming agent, and a foaming auxiliary agent. The foaming agent has a property of foaming in the presence of water. The foaming agent and the foaming auxiliary agent are not dissolved in the organic solvent, have an average particle size of 0.1 to 60 μm, and are contained in a particle state. -Like base.
