PROBLEM TO BE SOLVED: To provide a cap defective fitting checking device which can detect a cap which has been diagonally fitted on a bottle container. SOLUTION: This cap defective fitting checking device 10 detects a defective fitting of a cap 1 which is fitted on the bottle container 2, and is equipped with an imaging device comprising an illumination 11 which casts light to the fitted cap, a CCD camera 13 which photographs the reflected light from the cap, and an image processing device 14 which judges the presence/absence of the detective fitting of the cap 1 by processing the image acquired by the imaging device. The image processing device 14 acquires the center of the cap by processing the image, acquires a region which is surrounded by double circles of specified radii from the center, and judges the presence/absence of the defective fitting of the cap 1 based on a signal of numerous picture elements in the region of the double circles.
