Abstract
A casing includes a first casing member and a second casing member. The first casing member is provided on a side with a fuse module mounting section having a side opening. The second casing member is provided on the same side as the first casing member with a relay module mounting section having a side opening and extending downward. An ECU mounting frame extends from a bottom wall of the second casing member. An ECU is disposed on a second side of a bottom wall of the second casing member and in parallel with the relay module mounting section. A fuse module is attached to the fuse module mounting section to receive fuses. A relay module is attached to the relay module mounting section to receive relays. The fuse module and relay module that generate heat are disposed on a side of the casing in a vertical direction.
