To provide an injection nozzle for blast, by which a workpiece can be sufficiently and nearly uniformly machined.
The injection nozzle 1 for blast includes: a nozzle body 2 comprising a machining fluid chamber 21, a machining fluid introducing path 22 that communicates with the lower part of the machining fluid chamber 21, and an elongated machining fluid injection port 23 that communicates with the lower part of the machining fluid introducing path 22 and that extends in one direction; and an air nozzle 3 arranged in the machining fluid chamber 21 and composed of an air chamber 31, an air introducing path 32 that communicates with the lower part of the air chamber 31, and an elongated air injection port 33 that communicates with the lower part of the air introducing path 32 and that extends in the same direction as the machining fluid injection port 23, wherein the air introducing path 32 has an elongated shape extending in the same direction as the air injection port 33 and is tapered toward the air injection port 33.
