Abstract: A heat transfer fin includes a fin body and a plurality of through-holes formed through the fin body and spaced apart from each other in a first direction. When a flow direction of combustion gas that is to flow along a surface of the fin body is referred to as a second direction, the fin body includes a distal surrounding part that surrounds a first distal area located at the farthest upstream side of each of the through-holes. The shortest distance between an inner and an outer boundary of the distal surrounding part that is obtained in an area of the distal surrounding part located at the farthest upstream side is smaller than the shortest distance between the inner and the outer boundary that is obtained in an area of the distal surrounding part located at the farthest downstream side.
