A home appliance includes a hairline. A manufacturing method for a home appliance including a hairline includes forming at least one plating layer on a base material; processing a transverse hairline on an upper surface of a plating layer by tilting a hairline processing wheel at a predetermined angle, and forming a coating layer on the hairline. A home appliance having corrosion resistance and anti-fingerprint properties is produced while generating a transverse hairline. In addition, it is possible not to perform a separate plating after hairline processing.
