To provide a peroral tablet for bowel cleansing which leaves no remains in the intestinal tract after bowel cleansing, which exhibits a dissolution property equivalent to that of conventional sodium phosphate-containing tablets including crystalline cellulose, and which is a small-size agent readily taken by a subject. The peroral tablet for bowel cleansing containing the following ingredients (A) and (B): (A) 80 to 95 mass % of sodium phosphate, and (B) (B1) 7 to 11 mass % of hydroxypropyl cellulose which has such a particle size that >=99% of the particles thereof pass through a mesh having an opening of 350 mum and whose 2-mass % aqueous solution has a viscosity of 2.0 to 10.0 mPa.s, (B2) 5 to 13 mass % of hydroxypropyl cellulose which has such a particle size that >=99% of the particles thereof pass through a mesh having an opening of 150 mum and whose 2-mass % aqueous solution has a viscosity of 3.0 to 5.9 mPa.s, or (B3) 7 to 11 mass % of hydroxypropyl cellulose which has such a particle size that >=99% of the particles thereof pass through a mesh having an opening of 150 mum and whose 2-mass % aqueous solution has a viscosity of 6.0 to 4,000 mPa.s, and having a water-insoluble ingredient content of 5 mass % or less.
