Provided is a nitride semiconductor laser diode and a method for manufacturing the same. The method includes the steps of: a) forming a nitride semiconductor layer by orderly evaporating a substrate, an undoped GaN layer, an n-type layer, a multi-quantum well (MQW), an electron blocking layer (EBL) and a p-type layer; b) eliminating the substrate and the undoped GaN layer in the nitride semiconductor layer by lapping the substrate and the undoped GaN layer; and c) forming a ridge structure on the n-type layer. According to the present invention, a ridge structure is easily formed on an n-type layer, I-V characteristics are improved, heat generation is suppressed and an operational lifetime is extended.
