PROBLEM TO BE SOLVED: To provide a small-sized tablet useful as a calcium supplement which has not only properties such as moldability in preparing the tablet and hardness required for the tablet, but also excellent disintegrability in taking, and a tablet using the anhydrous calcium hydrogen phosphate as a filler.SOLUTION: There is provided a tablet which contains: (a) spherical anhydrous calcium hydrogen phosphate having an average particle diameter of 50 to 100 μm, and BET specific surface area of 5 to 30 m/g; and (b) crospovidone having an average particle diameter of 20 to 40 μm, which is a tablet in which the (a) component is 65.0 to 98.0% and the (b) component is 1.5 to 5.0% based on the total weight of the tablet as a reference, tensile strength is 1.2 to 2.2 MPa, and average disintegration time is 2 to 7 seconds. |
