The present invention relates to: an exterior panel for home appliances, having excellent reflectivity and durability and being applicable to the exterior of various home appliances; a home appliance comprising the exterior panel; and an exterior panel manufacturing method. Specifically, the exterior panel for home appliances comprises: an aluminum substrate which has, on one surface thereof, an engraved pattern having a predetermined width and depth, and which has micro-unevenness formed along the surface of the engraved pattern; a porous aluminum oxide layer formed on the engraved pattern; and a sealing layer for blocking a plurality of pores on the porous aluminum oxide layer, wherein the edge of the aluminum substrate is chamfered (C) or rounded (R). La présente invention concerne : un panneau extérieur pour appareils domestiques, ayant une excellente réflectivité et une excellente durabilité et pouvant être appliqué à l'extérieur de divers appareils domestiques ; un appareil domestique comprenant le panneau extérieur ; et un procédé de fabrication de panneau extérieur. En particulier, le panneau extérieur pour appareils domestiques comprend : un substrat d'aluminium qui a, sur l'une de ses surfaces, un motif gravé ayant une largeur et une profondeur prédéterminées, et qui présente une micro-irrégularité formée le long de la surface du motif gravé ; une couche d'oxyde d'aluminium poreuse formée sur le motif gravé ; et une couche d'étanchéité pour boucher une pluralité de pores sur la couche d'oxyde d'aluminium poreuse, le bord du substrat d'aluminium étant chanfreiné (C) ou arrondi (R). 본 발명은, 다양한 가전기기의 외관에 적용할 수 있는 반사율 및 내구성이 우수한 가전기기용 외장 패널, 외장 패널을 포함하는 가전기기 및 외장 패널의 제조방법에 관한 것이다. 구체적으로, 상기 가전기기용 외장 패널은 일면에 소정의 폭 및 깊이를 갖는 음각 패턴이 형성되고, 상기 음각 패턴의 표면을 따라 미세 요철이 형성된 알루미늄 기판; 상기 음각 패턴에 형성된 다공성 산화알루미늄 층; 및 상기 다공성 산화알루미늄 층의 복수의 기공을 막도록 형성된 실링층을 포함하며, 상기 알루미늄 기판의 테두리는 챔퍼링(Chamfering; C) 형상 또는 라운딩(Rounding; R) 형상을 가진다.
