To provide a molded article inspection device capable of accurately determining whether or not a molded article has a defect.SOLUTION: A molded article inspection device (1) for determining whether or not a molded article (3) molded by a molding machine (2) has a defect includes a thermography camera (7) for imaging the temperature distribution of the molded article (3) taken out from the molding machine (2), and a determination machine (8) for determining whether or not the molded article (3) has the defect from the temperature distribution of the molded article (3) imaged by the thermography camera (7). The thermography camera (7) and the determination machine (8) are connected through transmitter/receivers (9 and 10). Further, the molded article inspection device has the same number of thermography cameras (7) as the number of molded articles (3) simultaneously molded by the molding machine (2), and arrangement is performed so as to image the temperature distribution of each molded article (3) by each thermography camera (7).SELECTED DRAWING: Figure 1 【課題】成形品の欠損の有無を正確に判定することができる成形品検査装置を提供すること。【解決手段】本発明では、成形機（２）で成形された成形品（３）の欠損の有無を判定する成形品検査装置（１）において、成形機（２）から取出した成形品（３）の温度分布を撮像するためのサーモグラフィーカメラ（７）と、サーモグラフィーカメラ（７）で撮像した成形品（３）の温度分布から成形品（３）の欠損の有無を判定するための判定機（８）とを有することにした。また、本発明では、前記サーモグラフィーカメラ（７）と前記判定機（８）とを送受信機（９，１０）を介して接続することにした。さらに、本発明では、前記成形機（２）で同時に成形される成形品（３）の個数と同じ台数のサーモグラフィーカメラ（７）を有し、各サーモグラフィーカメラ（７）で各成形品（３）の温度分布を撮像するように配置することにした。【選択図】図１
