Zusammenfassung:PROBLEM TO BE SOLVED: To improve cooling efficiency by an impingement cooling mechanism.SOLUTION: The impingement cooling mechanism includes: a flat impingement hole 2 in which a gap between a cooling target 10 and an opposing member 20 is set to have an opening width D1 in a flow direction of a cross flow F that is larger than an opening width D2 in a direction orthogonal to the flow direction of the cross flow F.
