A bearing pad for a tilting-pad bearing includes a first member having a bearing surface and a second member disposed on a back surface side of the first member. At least one of a back surface of the first member or a front surface of the second member facing the back surface of the first member has a recess for forming a cavity between the first member and the second member. Preferably, the bearing pad further includes a support member disposed on a back surface side of the second member and tiltably supporting the first member and the second member, and the recess is formed over at least a part of an installation range of the support member in a plan view of the bearing pad.
