A cylindrical case includes a case main body, and a groove disposed annularly at one end of the case main body. A peripheral wall of the case main body is formed by alternately laminating a biaxial fabric layer, which includes a biaxial fabric of a non-crimp structure composed of reinforcing fiber bands having an orientation angle of ±45°, and a roving layer. A groove wall of the groove is formed by alternately laminating the biaxial fabric layer, which continues to the case main body side, and a triaxial fabric layer, which includes a triaxial fabric of a non-crimp structure composed of reinforcing fiber bands having an orientation angle of ±45° and a reinforcing fiber band having an orientation angle of 0°.
