The present invention relates to a diene-based rubber latex including a polymer aggregate and having an extra large diameter, a method for preparing same and a graft copolymer with a core-shell structure, including same and having excellent impact strength and surface properties. A diene-based rubber latex of which 14 wt% to 26 wt% has diameter of 100 nm to less than 300 nm, 62 wt% to 81 wt% has a diameter of 300 nm to less than 800 nm, and 5 wt% to 14 wt% has a diameter of 800 nm to less than 1000 nm, based on 100 wt% of total rubber particles. |
