A friction engagement element including: a friction member (91b) consisting primarily of a resin; and a metal member (93) having a sliding surface (93b) slidable on the friction member (91b). The friction member (91b) includes an aged layer (91d) at the outermost layer thereof and a hardened layer (91e) in abutment with the inner side of the aged layer (91d) in the thickness direction of the friction member (91b). The sliding surface (93b) of the metal member (93) has a plurality of recesses (95) and a transferred film (97) of the aged layer (91d) of the friction member (91b) transferred and adhered to the inside of the recesses (95) through sliding between the friction member (91b) and the metal member (93). |
