PROBLEM TO BE SOLVED: To provide an aqueous liquid housed bag which can softly fit a human body with a human head part sitting better without the propagation of vibration to make it suitable for water pillows, water beds or the like. SOLUTION: Laminated soft plastic sheets are fused along the peripheries thereof to form a bag 1 which houses an aqueous liquid and is sealed up. The inside of the bag is sectioned into a plurality of chambers 7 by melt bands 5 arranged in a network produced by fusing sheets facing each other on a contact surface and the plurality of chamber 7 are made to communicate between adjacent ones 7 through a liquid passage. The liquid passage is formed with discontinued parts arranged on each melt band 5. Thus, when any chamber 7 is pressurized from outside, the spillage of the liquid from the chamber 7 is delayed by a resistance in the fluid passage.
