The disclosed tablet that disintegrates rapidly in the mouth is for a drug having an unpleasant flavour, and is characterised by being hard enough so as to not interfere with handling between production and consumption and in particular remains hard after becoming moist. The tablet is small so the unpleasant flavour is not tasted, feels pleasant to take, has excellent disintegration properties in the mouth and elution properties in the alimentary canal and contains two or more types of particles.
