Claim 1:
2. The circuit board according to claim 1, wherein
the substrate includes a third section different from the first section and the second section;
the substrate includes a step surface provided by a difference between the position of the first principal surface of the first section and a position of a first principal surface of the third section in the thickness direction, exposed toward the first principal surface of the first section, and relating to the third section;
the plurality of mounting electrodes includes a group of mounting electrodes on the first principal surface of the third section to mount a component;
the group of mounting electrodes disposed on the first principal surface of the third section is provided on the first principal surface of the first section corresponding to an arrangement of terminals of the component;
the protective layer is disposed over the step surface relating to the third section and the first principal surface of the third section; and
for two mounting electrodes in the group of mounting electrodes disposed on the first principal surface of the third section, a separation distance between one of the two mounting electrodes nearer the step surface relating to the third section and the step surface relating to the third section is greater than or equal to a distance between the two mounting electrodes.
