The present invention relates to an absorbent article and the objective thereof is to provide an absorbent article which can favorably diffuse body fluids such as excreted urine in a longitudinal direction of a surface sheet, exhibits excellent intake of the body fluids diffused in the longitudinal direction, and allows less of the body fluids to pass back. In this absorbent article (1), a surface member (2) includes a central sheet member (21) and a pair of side sheet members (22, 23). The surface member (2) has a pair of first overlapping portions (A1) formed by overlapping the pair of side sheet members (22, 23) with the central sheet member (21) from a skin surface side. Each of the pair of first overlapping portions (A1) has a first joining portion (B1) that joins the central sheet member (21) and side sheet members (22, 23) and extends in a longitudinal direction (L), and first free edge portions (22a, 23a) of the side sheet members (22, 23), the first free edge portions (22a, 23a) extending along the first joining portion (B1) and protruding in a longitudinal axis direction (C).本發明係關於吸收性物品，其目的在於提供一種吸收性物品，其能夠使已被排出的尿液等的體液良好地朝表面薄片上的長度方向擴散，並且已朝前述長度方向擴散的體液之吸收變得良好，並且前述體液的逆流少之吸收性物品。本發明的吸收性物品(1)，表面構件(2)具備中央薄片構件(21)、及一對側部薄片構件(22)、(23)，前述表面構件(2)具有藉由將前述一對側部薄片構件(22)、(23)從肌膚面側重疊於前述中央薄片構件(21)所形成的一對第1重複部(A1)，前述一對第1重複部(A1)分別具有：將中央薄片構件(21)及側部薄片構件(22)、(23)接合並朝長度方向(L)延伸之第1接合部(B1)；和沿著該該第1接合部(B1)並朝長軸線(C)方向突出之前述側部薄片構件(22)、(23)的第1自由緣部(22a)、(23a)。
