Abstract: An inspection device 50 for a filter inspects the filter, which is provided to a flavor inhalation article. The filter is provided with a mouthpiece end, a solid material, and a communication path that communicates with the solid material and opens to the mouthpiece end. The inspection device is provided with: an illumination for irradiating an inspection light onto the mouthpiece end in an irradiation direction that extends along the axial direction X; a camera for photographing the peripheral surface of the filter in a photographing direction that extends along the radial direction Y of the filter; an image processing unit for processing an image photographed by the camera and detecting a shadow of the solid material; and, an assessment unit for assessing the presence or absence and the quality of the solid material 12 on the basis of the shadow detected by the image processing unit.
