    摘要: A ceramic matrix composite member to be used as a turbine blade (1) includes a principal part forming a blade part (2) and a dovetail part (6), and a subordinate part forming a platform part (4). A principal fiber in a ceramic fiber fabric (13) forming the principal part is a continuous fiber. An extension direction of the principal fiber is in parallel with a direction in which stress is applied. The ceramic fiber fabric (13) forming the principal part and a ceramic fiber fabric (15) forming the subordinate part are joined together and formed into an integrated three-pronged fiber fabric (11). The ceramic fiber fabric (13) forming the principal part and the ceramic fiber fabric (15) forming the subordinate part are integrated together by being set into a mold with the ceramic fiber fabric (15) forming the subordinate part folded at a desired angle to the ceramic fiber fabric (13) forming the principal part. Then, a ceramic matrix is formed in the obtained molded body.
