Zusammenfassung:	A cylindrical case includes a case main body 9C made of a composite material of reinforcing fibers impregnated with a thermosetting resin, and an outward flange 10 on the case main body 9C. The outward flange 10 includes: a bonding layer 11c to be bonded; a foundation layer 12 disposed on the bonding layer 11c; one flange constituting layer 13 having a leg layer 13a which is laminated from one slope surface 12a of the foundation layer 12 to the bonding layer 11c and a wall layer 13b which rises from the one slope surface 12a; and the other flange constituting layer 11 having a leg layer 11a which is laminated from the other slope surface 12b of the foundation layer 12 to the bonding layer 11c and a wall layer 11b which rises from the other slope surface 12b. The foundation layer 12 is formed by laminating roving layers, while the flange constituting layers 11, 13 are formed by laminating a plurality of biaxial fabric layers including a biaxial fabric 15 of a non-crimp structure. It is possible to secure high structural strength of the outward flange of a fan case which is made of a composite material consisting of reinforcing fibers and a thermosetting resin as the raw material.
