PROBLEM TO BE SOLVED: To obtain a readily producible tablet readily separable into four and certainly dividable into two parts. SOLUTION: The bottom 2 of a tablet 1 is separated into four zone faces a1 to a4 by two crossing dividing lines 7 and 8, anglesθ1 toθ4 between mutually adjoining zone faces a1 and a2, a2 and a3, a3 and a4 and a4 and al with the dividing lines 7 and 8 as boundaries are all made smaller than 180 deg. so as to make the center of the bottom 2 low and the circumference high. In the tablet 1, height h1 at a position at which the dividing line 8 reaches the circumference of the bottom 2 is made higher than height h2 at a position at which the dividing line 8 reaches the circumference of the bottom 2 and plane parts 9 positioned to bestride the dividing line 7 is formed in the vicinity of the position at which the dividing line 7 reaches the circumference of the bottom 2.
