To provide an on-vehicle battery pack which is capable of protecting a battery and also allows a reduction in weight.SOLUTION: An on-vehicle battery pack 20 comprises a battery tray 71 made up of a floor part 76, a right frame 96, and a left frame. The battery tray has: a battery placement region 115; and a shock absorption region 116 on the right side and a shock absorption region on the left side. A battery module 62 is mounted on the battery placement region. The shock absorption regions on the right and left sides are provided on the outside of the battery placement region in the vehicle width direction. The right frame and the left frame are made thinner than the shock absorption regions on the right and left sides. In their lower portions, the shock absorption regions on the right and left sides each have an easily deformable part 118.SELECTED DRAWING: Figure 8 【課題】バッテリを保護でき、さらに軽量化を図ることができる車両搭載用電池パックを提供する。【解決手段】車両搭載用電池パック２０は、床部７６、右側フレーム９６および左側フレームで構成されたバッテリトレー７１を備えている。バッテリトレーは、電池配置領域部１１５と、右側の衝撃吸収領域部１１６および左側の衝撃吸収領域部と、を有する。電池配置領域部にはバッテリモジュール６２が載置されている。左右側の衝撃吸収領域部は、電池配置領域部の車幅方向外側に設けられている。右側フレームおよび左側フレームは、右左側の衝撃吸収領域部より薄肉に形成されている。また、右左側の衝撃吸収領域部は、下部に易変形部１１８が形成されている。【選択図】図８
