PROBLEM TO BE SOLVED: To provide a method for inspecting blasting conditions, which can prevent faultly blasting beforehand by highly accurately inspecting changes in varying blasting conditions as time passes. SOLUTION: The surface roughness obtained by blasting a work-piece to be inspected under blasting conditions showing the limit of allowance is specified as critical surface roughness by using surface roughness parameters, and a surface roughness parameter is obtained by measuring the surface shape of the work-piece to be inspected after being blasted . Inspection is made to determine whether the blasting conditions under which the blasting was made to the work-piece to be inspected are those within an allowance range by comparing the surface roughness to be inspected with the critical critical surface roughness mentioned above based on the parameter.
