PROBLEM TO BE SOLVED: To provide a powder press forming apparatus that can uniform a filling density and form an inexpensive ceramic substrate formed body. SOLUTION: In the powder press forming apparatus 10 which includes: a mold composed of a die 14, a lower punch 15 and an upper punch 16; and a feeder 18 for filling ceramic granulating powder 12 in a space 17 formed by the upper face of the lower punch 15 and the wall face of a through hole 13, and forms a ceramic substrate formed body 11 by filling the ceramic granulating powder 12 in the space 17 and by press-forming with the lower punch 15 and the upper punch 16, the feeder 18 is composed of a box body with the bottom made an opening 19, and is provided with a levelling plate 23 which makes the ceramic granulating powder 12 supplied from the opening 19 into the space 17 flush with the upper face of the die 14, which is pressurized through a pressurizing body 22 from the inside of the tip end wall bottom face of the box body, which is erected projectingly from the tip end wall bottom face.
