1. A circuit board on which a first set or a second set is exclusively mounted, wherein the first set includes at least a first integrated circuit and a first electric element, and the second set including at least a second integrated circuit and a second electric element, the circuit board comprising:
an integrated circuit (IC) attachment part to which the first integrated circuit or the second integrated circuit is attached;
a first attachment part to which the first electric element is attachable and that includes at least a first pad and a second pad;
a second attachment part to which the second electric element is attachable and that includes at least a third pad and a fourth pad;
a first conductor pattern configured to electrically connect the IC attachment part and the first pad of the first attachment part;
a second conductor pattern configured to electrically connect the IC attachment part and the third pad of the second attachment part; and
a third conductor pattern configured to electrically connect the second pad of the first attachment part and the fourth pad of the second attachment part,
wherein, in a case where the first electric element is not mounted, the first pad and the second pad of the first attachment part are opened so as not to be electrically conductive with each other, and
wherein, in a case where the second electric element is not mounted, the third pad of the second attachment part and the second pad are opened so as not to be electrically conductive with each other.
