1. A decorative molded article that transmits a radio wave handled by a wireless device that performs at least one of transmission and reception of the radio wave, the decorative molded article illuminating a specific portion thereof by a light irradiated from a first light emitting device, the decorative molded article comprising:
a molded body formed into a predetermined shape, the molded body containing a translucent polymer that allows transmitting of the radio wave therethrough and that allows transmitting of the light therethrough;
a first reflective layer formed on a back surface of the molded body and having a first opening portion at a position not overlapping with the specific portion of the decorative molded article, (a) wherein the first reflective layer (i) reflects the light and (ii) transmits the radio wave therethrough, and (b) wherein the first opening portion transmits the light therethrough;
a decorative sheet bonded to a front surface of the molded body simultaneously with molding, the decorative sheet including, from front to back (a) a translucent film that transmits the radio wave therethrough and that transmits the light therethrough; (b) a shielding layer fixedly secured to the translucent film, wherein the shielding layer (i) transmits the radio wave therethrough and does not transmit the light therethrough and (ii) has a second opening portion that transmits the light therethrough, the second opening portion at a position overlapping with the specific portion and not overlapping with the first opening portion, and (c) a second reflective layer formed between the molded body and the shielding layer, wherein the second reflective layer (i) transmits the radio wave therethrough and reflects the light and (ii) has a third opening portion, wherein the third opening portion is located at a position overlapping with the specific portion and not overlapping with the first opening portion, and the third opening portion transmits the light therethrough; and
a first coloring unit that transmits the radio wave therethrough and colors the light to generate a first colored light; wherein
the decorative sheet, the first reflective layer, and the molded body form a light guide path that (a) guides the light from the first opening portion to the first coloring unit, thereby producing the first colored light and (b) guides the first colored light through the third opening portion, through the second opening portion, and through the translucent film to illuminate the specific portion.
