The invention provides a laminated busbar comprising a positive busbar and a negative busbar. The positive busbar comprises a positive power connection terminal and a positive body, wherein the positive power connection terminal comprises a positive connection terminal panel. The negative busbar comprises a negative power connection terminal and a negative body, wherein the negative power connection terminal includes a negative connection terminal panel. The panel surface side of the positive connection terminal panel faces the panel surface side of the negative connection terminal panel. Thelaminated busbar generates less heat, quickly dissipates heat, and has a long creepage distance and safe and good performance. There is also provided a power module comprising a power device, a capacitor device and the laminated busbar. The power module, because of using the laminated busbar, generates less heat, quickly dissipates heat, and has a long creepage distance. A vehicle is also providedincluding the power module. The use of the power module which generates less heat, quickly dissipates heat, and has a long creepage distance and safe and good performance contributes to ensuring theuse safety of the vehicle.
