Provided is a sliding member (1) for a journal bearing. The sliding member includes a back-metal layer (2) and a sliding layer (3), and has a partially cylindrical shape. The sliding layer (3) includes a synthetic resin (4) and has a sliding surface (30). The sliding layer (3) has a linear expansion coefficient KS in a direction parallel to a circumferential direction of the sliding member, a linear expansion coefficient KJ in a direction parallel to a center axis direction of the sliding member, and a linear expansion coefficient KT in a direction perpendicular to the sliding surface (30), and the linear expansion coefficients KS, KJ, and KT satisfy the following relations (1) and (2): Relation (1): 1.1 ≤ KS/KJ ≤ 2; and Relation (2): 1.3 ≤ KT/{(KS + KJ)/2} ≤ 2.5. |
