Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress a frost amount generated on the cooling fin surface of a heat exchanger, and effectively remove generated frost.SOLUTION: A heat exchanger 10 with a defrosting device includes: a heat exchange body 11 that has a cooling fin 12, and a pipeline 15 attached to the cooling fin 12; and a metal mesh 25 that is provided on the outer periphery of the cooling fin 12 of the heat exchange body 11. The metal mesh 25 is obtained by etching a metal base material, and has a mesh opening 25a and a rib 25b. An average diameter d of the mesh opening 25a is 50-300 μm, and a width l of the rib is 50-500 μm. 【課題】熱交換器の冷却フィン表面に生成される霜の量を抑え、かつ生成された霜を効果的に除去する。【解決手段】除霜装置付き熱交換器１０は冷却フィン１２と、冷却フィン１２に取付けられた配管１５とを有する熱交換器本体１１と、熱交換器本体１１の冷却フィン１２外周に設けられた金属メッシュ２５とを有する。金属メッシュ２５は金属基材をエッチング加工して得られ、メッシュ開口２５ａと、リブ２５ｂとを有する。メッシュ開口２５ａの平均直径ｄは５０μｍ〜３００μｍ、リブの幅ｌは５０μｍ〜５００μｍとなっている。【選択図】図２
