To provide a metallic worked product which is excellent in dimensional accuracy after working and prevents the lowering of a die life, and to provide a method and an apparatus for manufacturing the metallic worked product.

The metallic worked product 1 is formed so that a sectorial part has a curved tubular shape by using a metallic sheet including the sectorial part as a starting material 2 and bending it so as to make a pair of circular-arcuate end faces 2a, 2b of the sectorial part opposed each other, wherein engagement parts 4 consisting of tongue parts 4a, 4b for controlling the mutual shifting of a pair of opposite circular-arcuate end faces in the longitudinal direction are formed in the terminal part of the sectorial part.
