A smart key for a vehicle includes: a base part; a first terminal part coupled to the base part and which makes contact with a first electrode of a battery so as to be electrically connected to the battery; a second terminal part disposed facing the first terminal part to form an insertion part where the battery is inserted and which makes contact with a second electrode of the battery to be electrically connected to the battery; a separation prevention part which extends from the second terminal to the base part and which abuts the side surface of the battery to prevent the battery from separating from the insertion part; and a pressure applying part which is connected to the second terminal part so as to enable contact with the battery and which maintains contact between the battery and the separation prevention part by an elastic restoring force.

Cell groups are electrically connected by effectively using the space within a housing. A housing of a battery pack has therewithin a partition wall which projects in a projecting direction. A first cell group has a plurality of battery cells on one side of the partition wall. A second cell group has a plurality of battery cells on another side. A first terminal block projects from a side of the first cell group toward a side of the second cell group more to a side in the projecting direction than the partition wall. A second terminal block projects from a side of the second cell group toward a side of the first cell group. A coupling bus bar has one end arranged on the first terminal block and another end arranged on the second terminal block, thereby electrically connecting the first cell group and second cell group.
