The invention provides a supporting device of a battery pack for a vehicle and an electric vehicle, which can improve the protection performance of the battery pack. A support device (10) for supporting a battery pack (30) is provided with a frame-side bracket (4), a battery-side bracket (5), and an elastic coupling part (6). The battery pack (30) has a first battery housing part (31) disposed in a first space (S1) between side members (41) constituting a trapezoidal frame (40) of a vehicle, and a second battery housing part (32) disposed in a second space (S2) below the first space (S1). The frame-side brackets (4) have first brackets (1) extending downward from the side members (41) to the outside in the vehicle width direction, and second brackets (2) connecting the first brackets (1) to each other below the battery pack (30). The battery-side bracket (5) is provided so as to protrude outward in the vehicle width direction from an outer end surface (32a) of the second battery housing section (32) in the vehicle width direction. The elastic connection part (6) elastically connects the frame-side bracket (4) and the battery-side bracket (5).
