To provide a wall surface structure of a reinforced soil structural body capable of being lightly constructed with a small number of members, facilitating the execution of work, and at the same time, fixing up and down wall surface panels for a connecting device of the reinforced soil structural body having the wall surface of a panel structure.

In the wall surface structure of the reinforced soil structural body 10 having the wall surface of the panel structure, a recess 21 is formed in the back of a wall surface panel 20, a plurality of through-holes 23 passing through up and down are formed in a horizontal projection section, a connecting metal fitting 33 is engaged with a wall surface panel back horizontal member 22 by inserting a connecting pin, a vertical member 41a is inserted in a plurality of connecting metal fittings in a state to project a horizontal member 41b of the front end of a reinforced body upward of the connecting metal fitting 33, a connecting bar 36 is inserted in an opening formed between the vertical member 41a of the front end of the reinforced body and the connecting metal fitting 33 to engage the reinforced body 13 with the connecting metal fitting 33. In other words, the wall surface panel 20 is combined with the reinforced body 13 by a connecting device 14.
