PROBLEM TO BE SOLVED: To provide a dry cell in which the electrolyte solution absorbing and impregnating performance of a high-density molded cathode material is improved, and a trend that an absorbed and impregnated volume is decreased is prevented, and the dryout of the electrolyte solution at the discharge of the dry cell is prevented, and high load discharging performance is improved by raising a utilization ratio of an active substance in the dry cell, and which can be applied to an electronic unit requiring high load discharging performance and a high load unit requiring large power consumption. SOLUTION: In the dry cell, a cathode material 2 on the surface of which cracks 13 are formed for promoting inflow an of an electrolyte solution and for holding the electrolyte solute, an anode material 4, an cylindrical separator and a bottom separator 5 arranged between the cathode material 2 and the anode material 4 and the electrolyte solution are all housed in a cell case 1, and an open mouth of the cell case 1 is sealed by a sealing body 8 provided with an anode current collector rod 9.
