What is claimed is: 1 . An aluminum plate having a plurality of through holes that penetrate in a thickness direction, wherein an average opening diameter of the through holes is 1 μm to 100 μm, a density of the through holes is 50 through holes/mm 2 to 2,000 through holes/mm 2 , and an inter-hole distance between adjacent through holes is 300 μm or less. 2 . The aluminum plate according to claim 1 , wherein an average of the inter-hole distances between adjacent through holes is 150 μm or less. 3 . The aluminum plate according to claim wherein the average opening diameter of the through holes is more than 5 μm and 80 μm or less. 4 . The aluminum plate according to claim 2 , wherein the average opening diameter of the through holes is more than 5 μm and 80 μm or less. 5 . The aluminum plate according to claim 1 , wherein a percentage of the through holes having an opening diameter of 5 μm or less is 50% or less. 6 . The aluminum plate according to claim 4 , wherein a percentage of the through holes having an opening diameter of 5 μm or less is 50% or less. 7 . The aluminum plate according to claim 1 , comprising: a metal layer made of a metal plate covering at least an inner surface of the through holes. 8 . The aluminum plate according to claim 6 , comprising: a metal layer made of a metal plate covering at least an inner surface of the through holes.
