PURPOSE:To provide a steam generating convection-preventive plate for cure of concrete wherein steam can be generated for a long time by a simple structure with a small quantity of heating power. CONSTITUTION:A steam generating convection-preventive plate 1 for cure of concrete is placed by being dipped in water in a pot 14 heated from below under a state wherein it is filled with water. An opening part 3 is provided to a bottom part of the pot 14, and a blockaded part 4 is provided to its upper part. A funnel shape connected to steam discharging pipe is provided to its tip. A pressure pot 12 is inserted into an upper part of a cylindrical can body 1, and a kerosene burner 15 is stored in its lower part. A funnel like steam generating convection-preventive plate wherein water is little by little introduced to the bottom part of the pressure pot 12, and steam boiled by heating with the kerosene burner 15 is blown out to an upper part of the pressure pot 12 via a steam discharging thermal insulating pipe 5, is inverted in the bottom part of the pressure pot 12. A steam nozzle 20 carrying steam to a concrete objective material is provided to a top cover 13 of the pressure pot 12.
