PROBLEM TO BE SOLVED: To provide an anchor profile obtaining method and device for it, which reproduce a desired anchor profile without depending on worker's intuition in blasting work using a blast medium. SOLUTION: After a test piece (TP) is set in a case 204, while sponge blast medium is injected from a nozzle 12 for the TP, the nozzle 12 is moved at a predetermined speed along a slit 202. Thus, an anchor profile with a predetermined length is formed on TP. This test is performed while the kind of blast medium and the injection conditions of the blast medium are changed and combined, thereby obtaining TP where an anchor profile is formed by each condition. The anchor profiles of a number of these TPs are measured by measuring devices such as a stylus inspection device, a roughness measuring device and a replica tape, and the measurement values and various conditions corresponding thereto are stored as data in a recording part of a computer.
