To provide: a bipolar type secondary battery in which vibration durability is improved; a battery pack connected by a plurality of these; and a vehicle on which these are mounted.
The bipolar type secondary battery has a wiring circuit board 300 having a comb shape equipped with a plurality of teeth 301 which are inserted between laminated current collectors 230 and electrically connected to either of the opposing current collectors, and equipped with a shaft which supports a plurality of teeth and has the output end to output an electric potential of a plurality of teeth. The teeth 301 consists of a base part 301b in which a conductive material 303 is covered with insulation materials 304a, 304b, and a tip part 301a in which the conductive material is exposed. The teeth and the current collectors are electrically connected via an electroconductive elastic body installed between the tip part of the teeth and the current collectors.
