Abstract

A circuit board includes a substrate including first and second sections with different thicknesses, a protective layer, and mounting electrodes. The substrate includes a step surface connecting a first principal surface of the first section and a first principal surface of the second section. The mounting electrodes are on the first principal surface corresponding to an element to be mounted. The protective layer is disposed over the first principal surface, the step surface, and the first principal surface. The separation distance between the mounting electrode and the step surface is greater than or equal to the terminal-to-terminal distance between the mounting electrode and the mounting electrode.
