Abstract:
1. An inspection apparatus which detects an amount of misalignment, from a predetermined mounting position, of a component mounted on a surface of a panel through an adhesive which contains conductive particles, said inspection apparatus comprising: an illuminator which is provided on a bottom surface side of the panel which is opposite to a side of the panel on which the component is mounted, and illuminates with light a panel recognition mark formed on the panel and a component recognition mark formed on the component; a camera which is provided on a side of the panel opposite to said illuminator and captures an image of the panel recognition mark and an image of the component recognition mark which are illuminated with the light; and a calculation unit configured to calculate, using the images captured by said camera, an amount of misalignment in a positional relationship between the panel recognition mark and the component recognition mark from a predetermined positional relationship, wherein said illuminator emits light in an amount which causes halation in the images, the light having a wavelength that allows the light to pass through the panel and the component but does not allow or does not easily allow the light to pass through the conductive particles.
