A bearing pad for a tilting pad bearing is provided with a first member having a bearing surface, and also with a second member provided on the rear surface side of the first member. The rear surfaceof the first member and/or the surface of the second member, which faces the rear surface of the first member, has a recess which forms a cavity between the first member and the second member. Preferably, the bearing pad is further provided with a support member provided on the rear surface side of the second member and supporting the first member and the second member in a tiltable manner. In a plan view of the bearing pad, the recess is formed in at least a part of the area where the support member is installed. 可倾瓦块轴承用的轴瓦具备：具有轴承面的第一构件、以及设置在第一构件的背面侧的第二构件，第一构件的背面以及与第一构件的背面对置的第二构件的表面中的至少一方具有用于在第一构件与第二构件之间形成空洞的凹部。优选的是，可倾瓦块轴承用的轴瓦还具备支承构件，其设置在第二构件的背面侧，且将第一构件以及第二构件支承为能够倾转，在俯视观察轴瓦时，凹部形成在支承构件的设置范围的至少一部分。
