The invention belongs to the field of high-pressure turbine guide blades, and relates to a high-pressure turbine guide blade which comprises a blade body, an upper edge plate, a second lower edge plate and an inner ring structure. A turbine inner ring is integrally arranged on the inner side of the second lower edge plate, the turbine inner ring and one end of the second lower edge plate jointly form a welding face, the other end of the turbine inner ring and the other end of the second lower edge plate jointly form a non-welding face, and the honeycomb ring is in welding fit with the inner ring face of the turbine inner ring. During mounting, the two groups of welding areas are welded, so that the whole mounting structure of the blade is compact, the mounting process is simple, and the connection is firm and stable; each group of honeycomb rings and one group of second lower edge plates are combined for welding, so that the welding is more convenient; cooling air is ejected out from the air outlet holes in t
