An anti-cockroach decorative structure and a manufacturing method thereof are disclosed. The manufacturing method comprises steps of: immersing at least one paper into the solution of a mixture of anti-cockroach agent and thermosetting resin taking the paper out of the solution and drying it to form an anti-cockroach paper layer, wherein the thermosetting resin forms a meshed structure on the surface of the anti-cockroach paper layer, and the molecules of the anti-cockroach agent have a dimension larger than that of the meshes of the meshed structure, so that these molecules can be located between the meshed structure and the surface of the anti-cockroach paper and fixing the at least one anti-cockroach paper onto at least one surface of a main body via a thermo-compression boding so as to form the anti-cockroach decorative structure with desired and enduring anti-cockroach effect.一種防蟑裝飾結構及其製造方法,該製造方法包括以下步驟:將至少一紙層浸入防蟑劑與熱固性樹酯之混合物溶液內;將該紙層移出該混合物溶液外,並加以烘乾,以形成至少一防蟑紙層;其中,前述熱固性樹酯係於防蟑紙層表面形成一網狀結構;前述防蟑劑之組成分子係大於前述網狀結構之網眼大小,藉以固定於前述網狀結構與防蟑紙層表面之間;以及將該至少一防蟑紙層以熱壓方式,固著於一本體層之至少一表面上,即可形成具有理想且持久之驅蟑效果之防蟑裝飾結構。1‧‧‧防蟑裝飾結構10‧‧‧本體層12‧‧‧防蟑紙層
