To provide a wall structure having functions of moisture discharge dew, condensation prevention, heat insulation, waterproof, etc.

A moisture discharging layer γ is arranged between an underlayer α, which comprises a skeleton 3 and an outside heat insulating layer B formed on the outside of the skeleton 3, and an exterior wall material A. An upper opening 7 and a lower opening 8 are formed at the upper and lower parts of the moisture discharging layer γ. Both of the upper opening 7 and the lower opening 8, or the upper opening 7 is sealed with a member having moisture permeability.
