Disclosed is a cylindrical battery cell, and a battery pack and a vehicle including the same. The cylindrical battery cell includes a jelly-roll type electrode assembly having a structure in which a first electrode plate and a second electrode plate, each having a sheet shape, are wound in one direction with a separator being interposed therebetween, the first electrode plate including a first uncoated region in which an active material layer is not coated at an end of a long side, the first uncoated region forming a plurality of winding turns with respect to a center of the electrode assembly and being exposed to the outside of the separator to be used as an electrode tab by itself; a battery can having an open portion in which the electrode assembly is accommodated and a partial closed portion provided at a side opposite thereto, the battery can being electrically connected to the second electrode plate; a current collector plate electrically connected to the first uncoated region of the first electrode plate and having a fusing portion that is cut off when an overcurrent flows; and a cell terminal connected to the current collector plate through a through-hole of the closed portion of the battery can.
