Abstract
This high pressure gas tank is a tank in which a fiber-reinforced resin layer is formed around an outer periphery of a tank liner by fibers impregnated with thermosetting resin being wound around the outer periphery of the tank liner. The fiber-reinforced resin layer includes an inside layer formed on the tank liner side, and an outside layer formed on an outer periphery of the inside layer. The inside layer is formed as a dense layer, while the outside layer is formed as a layer that is less dense than the inside layer by forming a larger number of airspaces in the outside layer than there are in the inside layer.
