The present invention provides a set of electrode plates for rolled electrochemical component and a cell comprising it. The set of electrode plates comprises a stripe-shaped first electrode plate, a stripe-shaped second electrode plate and a stripe-shaped separator, said separator being positioned between the first electrode plate and the second electrode plate, and these three being revolved into a roll in the length direction, wherein said first electrode plate comprising a stripe-shaped first collector and the active material coated on the surface of said first collector, said second electrode plate comprising a stripe-shaped second collector and the active material coated on the surface of said second collector, a first exposed portion with a predetermined width on which the active material are not coated being formed on at least one of two terminals in a width direction of the first electrode plate to constitute a first collecting section, a second exposed portion with a predetermined width on which the active material are not coated being formed on at least one of two terminals in a width direction of the second electrode plate to constitute a second collecting section, a structure for preventing sharp crippling is formed on at least one of said first collecting section and said second collecting section in at least the innermost periphery of the set of electrode plates. Hence, a high quality component having reliable and stable electrical connection between the collecting section and the collecting plate thereof and prevented from inner short-circuit in the set of roll-shaped electrode plates can be obtained.
