The purpose of the present invention is to provide a tablet, and a production method thereof, which has a high absorption rate of spherical adsorptive carbon for oral administration, and a high uniformity of the spherical adsorptive carbon for oral administration and a binder additive. This purpose is met with: a tablet characterized in that the ratio between the maximum value and the minimum value of the additive volume fraction per 1 mm3 in five prescribed rectangular columns is less than or equal to 100； a tablet characterized in that the relative standard deviation of the volume fraction of three prescribed divided cubic bodies is less than or equal to 5%； or a tablet characterized in that the ratio between the maximum value and the minimum value of the additive volume fraction per 1 mm3 in five prescribed rectangular columns is less than or equal to 100 and in that the relative standard deviation of the volume fraction of three prescribed divided cubic bodies is less than or equal to 5%.本發明之目的係在於，提供一種口服給藥用球狀吸附炭之收穫率高，且口服給藥用球狀吸附炭及黏合用添加劑之均勻性高的片劑及其製造方法。上述課題可以透過下述片劑而解決，該片劑的特徵在於：規定的5個棱柱的每1mm3的添加劑體積率的最大值及最小值的比值為100以下；規定的3個分割體的立方體的體積率的相對標準偏差為5%以下；或者規定的5個棱柱的每1mm3的添加劑體積率的最大值及最小值的比值為100以下，且規定的3個分割體的立方體的體積率的相對標準偏差為5%以下。
