Abstract
A battery pack has a unit cell packaged by a package material of a laminate type, an outer case which accommodates the unit cell therein, and a vibration isolation device which attenuates vibrations inputted to the outer case and transmitted to the unit cell by pressing one side surface of the unit cell. The vibration isolation device is disposed between the unit cell and the outer case, and includes a first press structure which presses the one side surface of the unit cell. The first press structure is constituted by connecting one surface of the outer case, the one surface facing to the one side surface of the unit cell, and a press plate abutting against the one side surface of the unit cell with an elastic member interposed therebetween.
