To improve, in an electric vehicle that has a battery pack placed below a floor panel, the energy absorption performance of an EA material.SOLUTION: An electric vehicle includes: a pair of rockers 32 that extend in a vehicle back-and-forth direction; a floor panel 30 that extends between the pair of rockers; a battery pack 24 that is positioned below the floor panel; and an energy absorption material (EA material) 40 arranged outside the battery pack in a vehicle widthwise direction. The energy absorption material includes: a first component 42 that is fastened to the battery pack; and a second component 44 that is coupled to the external side of the first component in the vehicle widthwise direction, and extends up to the side below the rockers. The first component is thicker than the second component. Moreover, a boundary between the first component and the second component is positioned inwardly in the vehicle widthwise direction relative to the rockers.SELECTED DRAWING: Figure 2 【課題】フロアパネルの下方にバッテリパックが配置された電動車両において、ＥＡ材のエネルギー吸収性能を向上する。【解決手段】電動車両は、車両前後方向に延びる一対のロッカ３２と、一対のロッカの間を延びるフロアパネル３０と、フロアパネルの下方に位置するバッテリパック２４と、バッテリパックの車幅方向外側に配置されたエネルギー吸収材（ＥＡ材）４０とを備える。エネルギー吸収材は、バッテリパックに固定された第１部品４２と、第１部品の車幅方向外側に連結されているとともにロッカの下方まで延びる第２部品４４とを有する。第１部品の肉厚は、第２部品の肉厚よりも大きい。そして、第１部品と第２部品との間の境界は、ロッカよりも車幅方向内側に位置する。【選択図】図２
