Abstract

A cooling structure, a gas turbine combustor, and a method of manufacturing the cooling structure are provided, to attain a high the cooling efficiency without increasing a manufacturing cost. The cooling structure includes: a first member as a cooling object having a first plane; and a second member arranged above the first plane to have a second plane to oppose to the first plane such that a passage is formed between the first plane and the second plane for a cooling medium to flow. Said first member comprises a plurality of prominences which extend upwardly from the first plane, and each of the plurality of prominences extends to be inclined along a direction in which the cooling medium flows. A clearance between the second plane and a tip of the each prominence is set such that a heat transfer rate between the cooling medium and the first member becomes larger than a heat transfer rate when each prominence extends upwardly in a vertical direction from the first plane.
