A laterally diffused metal oxide semiconductor device includes: a substrate (10); a buried layer region (32) in the substrate; a well region (34) on the buried layer region (32); a gate region on the well region; a source region (41) and a drain region (43) which are located at two sides of the gate region; and a super junction structure. The source region (41) is located in the well region (34); the drain region (34) is located in the super junction structure; the gate region comprises a gate oxide layer and a gate electrode on the gate oxide layer; and the super junction structure comprises a plurality of N-columns and P-columns, wherein the N-columns and the P-columns are alternately arranged in a direction which is horizontal and is perpendicular to the direction of a connecting line between the source region and the drain region, each N-column comprises a top-layer N-region (23) and a bottom-layer N-region which are butted vertically, and each P-column comprises a top-layer P-region (24) and a bottom-layer P-region which are butted vertically.
