PROBLEM TO BE SOLVED: To obtain an earth-retaining wall in which safety during construction is high, workability is improved and the quantity of steel to be used is reduced.SOLUTION: An earth-retaining wall is constructed by installing a plurality of pillar bodies at intervals, bridging adjacent pillar bodies with a wall surface material 3 and back-filling the wall surface material 3, the pillar bodies and a slope with a back-filling material. The pillar body is comprised of a tubular pillar material 13 and a filling material which fills the tubular pillar material 13. The tubular pillar material 13 is formed from a front surface material 11 forming a portion closer to a front face than a position to mount the wall surface material 3 and a rear surface material 12 forming portions closer to a side face and a rear face excluding the front surface material. The front surface material 11 is comprised of a plate surface material, and the rear surface material 12 is comprised of a see-through surface material having see-through property. Since the rear surface material 12 has the see-through property, if there is the risk of collapsing an excavation slope behind the tubular pillar materials by being attacked with rainfall of a typhoon or the like on the stage where the tubular pillar materials are not filled with the filling materials yet, an excavation surface is observed and appropriate handling can be performed promptly, thereby improving safety during construction.
