Decorative part for vehicle and method for manufacturing same

A method for manufacturing a vehicle decorative part, wherein the vehicle decorative part includes

• a decorative main body that is configured to be attached to a vehicle at a front side in a transmission direction of millimeter waves from a millimeter wave radar to decorate the vehicle and has a millimeter wave transparency, and
• a sheet-shaped heater having a heating element that emits heat when energized, the decorative main body includes
• a transparent member, which is made of a plastic, and
• a base, which is made of a plastic and located at a rear side in the transmission direction of the transparent member, and
• the base is divided into a front base and a rear base, which is located at a rear side in the transmission direction of the front base,
• the method comprising, after the transparent member and the front base are formed sequentially, forming the rear base by insert molding using, as an insert, an intermediate molded part in which a main portion of the heater including the heating element is located at a rear side in the transmission direction of the front base,
• wherein
• the front base includes a general section and a protrusion that protrudes frontward in the transmission direction relative to the general section,
• the insert molding is performed in a state where the heater includes a through section that extends through the heater in the transmission direction at a position separated at least from the heating element, and
• the insert molding is performed such that the through section of the heater communicates with a depression formed in a rear surface in the transmission direction of the front base at a position behind the protrusion.
