PROBLEM TO BE SOLVED: To solve the problem of various conventional body ventilators for ventilation with air jetted from a support surface on the body side, wherein a larger quantity of air is jetted from places closer to an air supply part so that the quantity of air to be jetted from a distant place tends to be small because the body ventilators are configured to jet air through a number of air jetting pores and through a highly air-permeable sheet-like material. SOLUTION: A ventilation part 4 made of a low-air-permeable sheet-like material 3 is disposed on the body side surface of a flat airbag 1 which can store air by an air-impermeable sheet-like material 2, and the air supply part 5 is disposed at an appropriate position in the flat airbag to solve the problem.
