The present invention provides a heat insulating wall, a heat insulating box, and a method for manufacturing the same, which have improved heat insulating properties as compared with the conventional one. A heat insulating housing includes a hollow wall body, and an open cell resin body filled in a heat insulating space which is a hollow portion of the wall body by integral foaming, and the open cell resin body includes a plurality of open cell resin bodies. Bubbles 47, a bubble film part, a bubble skeleton part 43, a first through hole formed so as to penetrate the bubble film part, and a second through hole formed so as to penetrate the bubble skeleton part 45, and the plurality of bubbles communicate with each other through the first through hole and the second through hole.
