【Task】 Provided is a polyester fiber structure having a good texture while having no drip at the time of combustion and having flame retardancy. [Solution] 2-10% by weight of a silicone resin (component A) represented by the following general formula (1) is contained in the polyester fiber structure, RSi (OH) m (OR A ) n O (3-mn) / 2 (1) [Wherein, R represents a monovalent organic group excluding a hydrogen atom and an alkoxy group, R A represents a monovalent organic group excluding an alkoxy group, and m and n are 0 <m <1, 0 ≦ n <1, 0 <m + n <1 that satisfies the range] One or two or more of boric acid, borax, and sodium polyborate (component B) are attached by 5 to 20% owf.
