Abstract
A substrate includes a base material, a first solder part disposed on a surface of the base material and used for connection to an electronic component, and a second solder part disposed on the surface of the base material and made of the same solder as that of the first solder part. The top surface of the first solder part is made to be a flat surface, and the maximum height of the second solder part from the surface of the base material is lower than the height of the flat surface of the first solder part from the surface of the base material. Thus, a substrate for which the kind of solder can be determined easily and with certainty, a device provided with this substrate, a method of manufacturing the substrate, and a determining method are provided.
