VEHICLE BATTERY PACK

A vehicle battery pack (10) includes: a battery case (20) in which a battery module (11) is built; a first electrical component (13) configured to convert electric power from the battery module (11); a second electrical component (14) configured to electrically connect the battery module (11) to the first electrical component (13); and a housing (30) configured to house the battery case (20), the first electrical component (13), and the second electrical component (14). The first electrical component (13) and the second electrical component (14) are arranged side by side on a vehicle front side and a vehicle rear side in a space formed on a lateral side of the battery case (20) in the housing (30) in a vehicle width direction, and are electrically connected to each other via a conductive member (15). The first electrical component (13) includes a first connection portion (13A) to which one end portion of the conductive member (15) is connected. The second electrical component (14) includes a second connection portion (14A) to which the other end portion of the conductive member (15) is connected. The first connection portion (13A) and the second connection portion (14A) are arranged such that height positions of the first connection portion (13A) and the second connection portion (14A) are different. And the conductive member (15) includes an inclined portion (15A) inclined to be higher from the second connection portion (14A) toward the first connection portion (13A).
