SUBSTANCE: group of inventions relates to a module of air cavities and an air mattress. The air cavity module inserted into the inflatable mattress contains a plurality of air cavities, each having a hollow portion formed therein and configured to be inflated due to the inflow of air or deflated due to the outflow of air, and a bottom skin connected to the lower sides of the air cavities and configured to block the hollow portion of each of the air cavities. The air cavity includes a top surface portion forming a top surface, a side surface portion joined to a top surface portion and forming a side surface, and a contact portion protruding upwardly from the center of the top surface portion. The air cavity includes a first connecting portion formed on an edge portion of the air cavity, where a portion of the upper surface and a portion of the side surface are connected to each other to connect a portion of the upper surface and a portion of the side surface to each other. The first connecting portion is formed to tilt from the upper surface portion to the lateral surface portion.
