This relay unit includes: a first bus bar; a relay electrically connected to the first bus bar; and an apparatus cover for covering the first bus bar and the relay. The apparatus cover includes: an upper member in a box shape having a covered upper end, the upper member having an opening formed in a lower end; and a lower member bonded to the upper member such that the opening of the upper member is covered with the lower member. The lower member is formed of a resin having heat conductivity that is higher than that of the upper member. The first bus bar is connected to the lower member via a first inner heat conductive sheet such that heat can be transferred to the lower member, said first inner heat conductive sheet being disposed between the first bus bar and the lower member.
