In an inspecting apparatus for a foreign matter for detecting a foreign matter got entered an object being inspected that contains a liquid product by inspecting the object being inspected optically with imaging means, a conical prism is disposed between the object being inspected and the imaging means. Consequently, it is possible to provide an inspecting apparatus for a foreign matter for use in a production line for manufacturing liquid products, such as drinks and liquid drugs, which can detect in a reliable manner whether a foreign matter has entered a liquid inside a container, such as a bottle or a PET bottle, and a foreign matter in a colored bottle or PET bottle or in a colored liquid as well.
