A ceramic green sheet containing 100 parts by mass of a cordierite powder having an average particle diameter of 1.0 to 5.0 mum and a BET specific surface area of 4.0 to 10.0 m<SUP>2</SUP>/g and 14.0 to 19.0 parts by mass of a binder. The ceramic green sheet is preferred to further contain 0.5 to 2.5 parts by mass of a dispersing agent and 5.0 to 9.0 parts by mass of a plasticizer relative to 100 parts by mass of the cordierite powder. The ceramic green sheet can be made, by firing, into a tape-shaped ceramic formed body which is dense and superior in thermal sock resistance.
