1. A circuit assembly comprising:
a main relay configured to be electrically connected between a load and a battery;
a pre-charge circuit connected in parallel with the main relay;
a heat transfer member; and
a case that accommodates the main relay and the pre-charge circuit,
wherein the heat transfer member includes a planar first heat transfer sheet in contact with the case,
wherein the pre-charge circuit includes a current-carrying portion configured to be connected to the main relay,
wherein the heat transfer member and the current-carrying portion are in contact with each other, and
wherein the heat transfer member includes a planar first heat transfer sheet in contact with the case such that the planar first heat transfer sheet and the case are contiguous.
