To inspect the weight of each individual object such as a microplastic efficiently with high accuracy.SOLUTION: One embodiment of an inspection device pertaining to the present invention comprises: a flattening unit (3) for compressively crushing a group of objects scattered on a stage to flatten so that a prescribed thickness is achieved; size acquisition units (41, 52) for acquiring information related to a size in a plane orthogonal to the thickness direction with regard to at least some of the objects included in the flattened group of objects; identification units (40, 50) for optically analyzing the objects before or after being flattened and identifying the type of resin included in the objects on the basis of the result of the analysis; and weight calculation units (51, 53) for finding information related to the weight of the objects using information about the type of resin obtained by the identification units and information related to the size.SELECTED DRAWING: Figure 1 【課題】マイクロプラスチック等の対象物の個々の重量を、効率良く且つ高い精度で以て検査する。【解決手段】本発明に係る検査装置の一態様は、ステージ上で散在する対象物群を圧潰して所定の厚さになるように平坦化する平坦化部（３）と、平坦化された前記対象物群に含まれる少なくとも一部の対象物について厚さの方向に直交する面内でのサイズに関連する情報を取得するサイズ取得部（４１、５２）と、平坦化される前又は後の前記対象物を光学的に分析し、その分析結果に基いて該対象物に含まれる樹脂の種類を識別する識別部（４０、５０）と、前記識別部により得られた樹脂の種類の情報と前記サイズに関連する情報とを利用して、前記対象物の重量に関連する情報を求める重量算出部（５１、５３）と、を備える。【選択図】図１
