A tunnel boring machine cutter comprises a base body, a groove formed in a cutting edge part of the base body and a blade arranged in the groove, and is characterized in that an abrasion resistant layer is arranged on the periphery of the groove, and a plurality of abrasion resistant blocks are arranged at the top of the base body. The tunnel boring machine cutter has the advantages of corrosion resistance, easiness in cleaning, solidness, low probability of deformation as well as durability due to the fact that the abrasion resistant layer and the abrasion resistant blocks are made of high-strength cemented carbide in a build-up welding manner.
