The present invention relates to a thermal insulation foamed sheet whose foaming height can be kept high by increasing an expansion ratio of foaming cells, thermal insulation foamed container using this and method for producing the same. In the thermal insulation foamed sheet according to the present invention, a foaming plane made of a foaming cell group is formed by heating the sheet in which a synthetic resin film is laminated on base paper and foaming the synthetic resin film using moisture contained in the base paper, and at least a part of the foaming plane is vacuum-suctioned so as to increase the foaming height of the foaming cell. Also, there can be made a thermal insulation foamed container having this foaming plane on at least its body section.
