PROBLEM TO BE SOLVED: To provide a wall face structure which can perform construction management for constructing a wall body having a desired thickness by being easily mortared in a proper lath net shape, in which the constructed wall body is high in rigidity by being integrated with a lath net, and which has stable wall magnification, a ventilation wall face body, and a construction method of these items.SOLUTION: In a construction method which fixes a mesh lath A with a stainless steel weld wire gauze as a raw material to a structure material or a sub-structure material, and forms a wall face by mortaring it so that the mesh lath A is embedded, the mesh lath A is formed by a first process in which the mesh lath is arranged at the structure body or the sub-structure body so as to progress along a longitudinal rib 12 side of the mesh lath A, and a trough part of the mesh lath is fastened by a stainless steel made stapler B, and a second process in which mortar is applied from a lateral rib 11 side of the mes
