A sliding member having more improved wear resistance is provided at a low cost. A sliding member is provided with: a substrate which is made of a nonwoven fabric; and a base resin which includes a phenol resin and which is impregnated into the substrate. The nonwoven fabric is preferably a bonded nonwoven fabric which is produced by a thermal bonding method, a binder method or the like and which has a strength that can tolerate the tension applied to the substrate in the step for producing the sliding member. It is preferable that the nonwoven fabric is made of a polyethylene terephthalate (PET) fiber which exhibits a high affinity for the phenol resin. Further, it is preferable that the phenol resin contains a chelating agent which can increase sites of crosslink with hydroxyl groups of the phenol resin.
