PROBLEM TO BE SOLVED: To provide a method for producing a shell PCa member which can bear the use of high fluidity concrete in the field and secure desired strength and a desired appearance. SOLUTION: In the method for producing the shell PCa member 1, an inner form in which the intermediate part of a peripheral hoop streak is arranged to be exposed to the inside of the shell PCa member is set in an outer form forming the shell PCa member. A hollow shell PCa member is manufactured by placing concrete between the outer form and the inner form. A core streak assembled in advance in the hollow shell PCa member is inserted slantingly toward the corner part of the peripheral hoop streak embedded in the hollow shell PCa member. Next, the core streak is rotated on the intermediate part side of the peripheral hoop stream and set at a prescribed position with the peripheral hoop streak. The inner form is formed from a split cylindrical form part and a corner form arranged in a polygonal edge part, and the installation channel of the peripheral hoop streak is formed in the cylindrical form part.
