A component mounter provided with a transfer inspection device that is adapted to inspect the transfer state of a fluid, which is one of solder, flux, conductive paste, or adhesive, which has been transferred onto the bumps on the bottom surface of a component by imaging the bottom surface of the component held by a suction nozzle with a camera and performing image recognition, comprising: a transfer inspection data creation device that is adapted to create transfer inspection data used when inspecting the transfer state of the fluid, the component mounter being characterized in that the transfer inspection data creation device includes an image processing means that is adapted to perform imaging with the camera of the bottom surface of the component being held by the suction nozzle before the fluid has been transferred to the bumps on the bottom surface of the component at multiple shutter speeds, then to acquire the multiple pre-transfer images captured at different shutter speeds, and to determine the pixel values of the pre-transfer bump portions by performing gray processing on each pre-transfer image, and that also is adapted to perform imaging with the camera of the bottom surface of the component after the fluid has been transferred to the bumps on the bottom surface of the component at the same multiple shutter speeds as pre-transfer, then to acquire the multiple post-transfer images captured at different shutter speeds, and to determine the pixel values of the post-transfer bump portions by performing gray processing on each post-transfer image; a shutter speed determining means that is adapted to determine the shutter speed used for inspection of the transfer state based on the pixel values of the post-transfer bump portions; and a transfer inspection data creation means that is adapted to create the transfer inspection data based on the pixel values of the post-transfer bump portions of the image captured with the shutter speed determined by the shutter speed determining means. a transfer inspection data creation device that is adapted to create transfer inspection data used when inspecting the transfer state of the fluid, the component mounter being characterized in that the transfer inspection data creation device includes an image processing means that is adapted to perform imaging with the camera of the bottom surface of the component being held by the suction nozzle before the fluid has been transferred to the bumps on the bottom surface of the component at multiple shutter speeds, then to acquire the multiple pre-transfer images captured at different shutter speeds, and to determine the pixel values of the pre-transfer bump portions by performing gray processing on each pre-transfer image, and that also is adapted to perform imaging with the camera of the bottom surface of the component after the fluid has been transferred to the bumps on the bottom surface of the component at the same multiple shutter speeds as pre-transfer, then to acquire the multiple post-transfer images captured at different shutter speeds, and to determine the pixel values of the post-transfer bump portions by performing gray processing on each post-transfer image; a shutter speed determining means that is adapted to determine the shutter speed used for inspection of the transfer state based on the pixel values of the post-transfer bump portions; and a transfer inspection data creation means that is adapted to create the transfer inspection data based on the pixel values of the post-transfer bump portions of the image captured with the shutter speed determined by the shutter speed determining means. <EOS>
