PROBLEM TO BE SOLVED: To provide an orally disintegrating tablet with a short disintegration time and with low friability.SOLUTION: An orally disintegrating tablet 10 comprises bulged parts 13 and 14 which respectively bulges toward outside from each circular plane 11 and 12 located on the up and down of a cylindrical form. Each plane 11 and 12 are located at the circumference adjacent to a cylindrical form peripheral surface 15, and in a section orthogonal to the planes 11 and 12, the length which is the shortest distance between the peripheral surface 15 and the bulged parts 13 and 14 is 0.01-0.09 mm. The orally disintegrating tablet 10 has a short disintegration time and low friability.SELECTED DRAWING: Figure 2
