PROBLEM TO BE SOLVED : To provide a fill structure which prevents wall panels formed in a staked state from being deformed by the earth pressure of a fill material, and a construction method for the fill structure. SOLUTION : In this fill structure 1, a retaining wall 5 in which a plurality of precast concrete panels 4 are stacked is formed on a foundation 3 on the downside of sloped natural ground 2; a fill layer 7 in which the fill materials 6 are stacked in a multistage shape is formed between the retaining wall 5 and the sloped natural ground 2; an earth-pressure-reducing buffer material 9 is filled between the fill layer 7 and the retaining wall 5; and an anchor material 10 from the retaining wall 5 is embedded in the fill layer 7.
