Solder printing inspection device, solder printing inspection method and method of manufacturing substrate

A solder printing inspection device that is placed on an upstream side of a component mounting machine that mounts an electronic component on solder that is printed on a substrate by a solder printing machine, and that inspects the solder on the substrate on which a thermosetting adhesive is applied, the solder printing inspection device comprising:
