a tub arranged inside the cabinet and capable of accommodating wash water; a drum arranged inside the tub and capable of accommodating laundry; and a door to open and close the insertion port, wherein the door comprises a first section made of a transparent material in at least a portion of a door cover and a second section made of an opaque material in at least a portion of the door cover; the first section comprises a first area which is coupled with the second section and a second area which is not coupled with the second section; and the second area appears a metallic color due to scattering of light. ### Claim 10 (depends on 9) The washing machine according to claim 9, wherein the first and second sections are formed along an edge of the door cover, the first section is located outside the door cover, and the second section is located inside the first section. ### Claim 11 (depends on 9) The washing machine according to claim 9, wherein a gap for scattering of light is defined between the first section and the second section. ### Claim 12 (depends on 9) The washing machine according to claim 9, wherein the first section comprises an oblique portion inclined inward of the washing machine by an angle of about 40° to 50°. ### Claim 13 (depends on 9) The washing machine according to claim 9, wherein the first section further comprises a roughened portion which has a protrusion portion protruding from an inner surface of the first section and a recessed portion recessed outward of the door cover from the inner surface thereof. ### Claim 14 A washing machine comprising: a cabinet defining an external appearance thereof and having an insertion port; a tub arranged inside the cabinet and capable of accommodating wash water; a drum arranged inside the tub and capable of accommodating laundry; and a door to open and close the insertion port, wherein: the door comprises a first section which is arranged in at least a portion thereof, and a second section which is injection-molded integrally with the first section; and an oblique portion is disposed at one side of at least one of the first and second sections, and is provided so as to visually distinguish a difference in external appearance between the cabinet and a door cover due to a difference in transmissivity of light generated by the oblique portion. ### Claim 15 (depends on 14) The washing machine according to claim 14, wherein the second section is located inside the first section. ### Claim 16 (depends on 14) The washing machine according to claim 14, wherein the oblique portion is formed to be inclined inward of the washing machine. ### Claim 17 (depends on 14) The washing machine according to claim 14, further comprising: a recessed portion configured such that at least a portion of the cabinet with which the door comes into contact is recessed inward of the washing machine, wherein the recessed portion comes into contact with a glass holder. ### Claim 18 A method of manufacturing a door of a washing machine, comprising: performing primary injection molding of a first section through which incident light penetrates; and performing secondary injection molding of a second section located inside the first section and configured such that at least a portion of the second section is projected through the first section. ### Claim 19 (depends on 18) The method according to claim 18, wherein the first section is made of a transparent material, and the second section is made of a colored opaque material. ### Claim 20 (depends on 18) The method according to claim 18, further comprising performing a cooling process for a predetermined time after the primary injection molding of the first section. ### Claim 21 (depends on 20) The method according to claim 20, further comprising performing a cooling process for a predetermined time after the secondary injection molding of the second section. ### Claim 22 (depends on 18) The method according to claim 18, wherein the first section comprises an oblique portion inclined by a predetermined angle. ### Claim 23 (depends on 18) The method according to claim 18, wherein the first and second sections are provided at a door cover coupled outside a door. ### Claim 24 (depends on 23) The method according to claim 23, further comprising performing a process via which, after the injection molding of the door cover, a glass is coupled to the door cover. ### Claim 25 (depends on 24) The method according to claim 24, further comprising performing a process via which, after the coupling of the glass to the door cover, a glass holder is coupled to the glass in order to fix the glass. ### Claim 26 A method of manufacturing a door of a washing machine, comprising: primarily injection molding a first section; and secondarily injection molding a second section inside the first section, wherein a portion of the second section is projected through the first section. ### Claim 27 (depends on 26) The method according to claim 26, wherein a molding material of the first section is translucent, and a molding material of the second section is opaque. ### Claim 28 (depends on 26) The method according to claim 26, wherein primarily injection molding the first section includes molding an oblique portion inclined by a predetermined angle. ### Claim 29 (depends on 26) The method according to claim 26, further comprising coupling the first and second sections and a glass to a glass holder.
