An inspecting apparatus(50) is provided which inspects whether or not a liquid absorbent particulate is deposited with a predetermined deposition pattern on an absorbent sheet-like member(1),the absorbent sheet-like member(1) having a continuous web(5) and a plurality of absorbent bodies(3),the continuous web(5) being transported along a transport direction, the absorbent bodies(3) being formed on one surface of the continuous web(5) in a spaced apart manner in the transport direction, each absorbent body(3) including the liquid absorbent particulate as a main material. The inspecting apparatus(50) includes: an imaging process section which is adapted to image, from one side of a surface of the absorbent sheet-like member(1), a region on the absorbent sheet-like member(1) where the absorbent body(3) is expected to exist, and that is adapted to produce data relating to a planar image of the region as planar image data of the absorbent body(3) an extracting process section which is adapted to extract a proper quantity region from the planar image by performing a binarization process on the produced planar image data based on a threshold value, the proper quantity region being an imaged region in which the liquid absorbent particulate is of a specified amount or more and a pass/fail determination process section that is adapted to perform a pass/fail determination process based on a value indicating a size of the proper quantity region.檢查在具有沿著搬送方向被搬送的連續纖維網、與以液體吸收性粒狀物作為主材,朝前述搬送方向分開間隔以預定的層積模樣形成在前述連續纖維網的單面的複數個吸收體之吸收性薄片狀構件,是否以前述層積模樣層積有前述液體吸收性粒狀物的檢查裝置。具有:攝像處理部,該攝像處理部是從前述吸收性薄片狀構件的單面側攝像在前述吸收性薄片狀構件之中前述吸收體必須存在的區域,而生成前述區域的平面影像的數據作為與前述吸收體的前述平面影像相關的數據;抽出處理部,該抽出處理部是依據閾值對所生成的前述平面影像數據進行二值化處理,藉此抽出攝像到在前述平面影像之中,有規定的基重以上的前述液體吸收性粒狀物的區域作為適量區域;以及良否判定處理部,該良否判定處理部是依據表示前述適量區域的大小的值,進行前述吸收體的良否判定。1‧‧‧吸收性薄片狀構件10‧‧‧製造裝置P5‧‧‧供給位置5‧‧‧表面纖維網(連續纖維網)Tr22‧‧‧圓周徑路22‧‧‧旋轉滾筒22a‧‧‧外周面20‧‧‧旋轉滾筒裝置Dc‧‧‧周向30‧‧‧SAP供給裝置SAP‧‧‧高吸收性聚合物(液體吸收性粒狀物)35‧‧‧接著劑塗布裝置7‧‧‧裏面纖維網(其他的連續纖維網)C22‧‧‧水平軸40‧‧‧熱密封裝置42‧‧‧上輥42a‧‧‧外周面G40‧‧‧輥間隙
