A composite vane body 11 formed of a composite material of a thermosetting resin or a thermoplastic resin, and reinforced fibers, and a metal sheath 12 that is bonded to a leading edge section 11A of the composite vane body 11 via a soft adhesive 13 to cover the leading edge section 11A are included, and an adhesive filling section 11a in which the soft adhesive 13 is filled, a plurality of leading edge side contact sections 11b that come into contact with a curved section 12b corresponding to a leading edge of the metal sheath 12, and a plurality of protrusions 11c that come into contact with a planar section 12c corresponding to a vane surface of the metal sheath 12, with at least a same height as a thickness of a layer of a requisite amount of the soft adhesive 13 filled in the adhesive filling section 11a are formed in the leading edge section 11A of the composite vane body 11. Attachment of the metal sheath to the leading edge section can be performed easily with high precision.
