A vehicle exterior part is configured to be arranged frontward of a millimeter wave radar device with respect to the transmission direction of millimeter waves. The vehicle exterior part includes an ornamental body, a light source that emits light, and a light diffuse reflection member. The light diffuse reflection member is millimeter wave-transmissive and diffuses and reflects light. The ornamental body includes a base and an ornamental layer. The base is millimeter wave-transmissive and diffuses and transmits the light. The ornamental layer is millimeter wave-transmissive and arranged frontward of the base with respect to the transmission direction. The light source, the ornamental body, and the light diffuse reflection member are arranged so that the light emitted from the light source is diffused and reflected by the light diffuse reflection member and directed toward the base.

Vehicle exterior part

An electromagnetic wave sensor cover includes a cover body. The cover body includes a base layer made of synthetic resin and permitting passage of an electromagnetic wave, one or more metal oxide layers permitting passage of the electromagnetic wave and being conductive, one or more low refractive index layers permitting passage of the electromagnetic wave and made of material that has a lower refractive index than material of the metal oxide layer, and two electrodes. The base layer includes a front surface and a rear surface in a transmission direction of the electromagnetic wave. The metal oxide layer and the low refractive index layer are laminated adjacent to each other in the transmission direction. A laminate of the metal oxide layer and the low refractive index layer is laminated on the front surface or the rear surface of the base layer.

Electromagnetic wave sensor cover

An electromagnetic wave sensor cover, applied to an electromagnetic wave sensor including a transmission unit and a reception unit, includes a cover main body portion that covers the transmission unit and the reception unit. The cover main body portion includes: a base material formed of a resin material and having a transmission property of an electromagnetic wave from the transmission unit; an undercoat layer formed on a rear surface of the base material and having the transmission property of the electromagnetic wave from the transmission unit; a heater portion that is formed of copper in a band shape on a rear surface of the undercoat layer, is configured to generate heat by being energized, and adheres to the base material via the undercoat layer; and a SiOcoating film having the transmission property of the electromagnetic wave from the transmission unit and covering the heater portion.

An electromagnetic wave transmissive cover is configured to be employed in a vehicle to which a sensor device is attached. The electromagnetic wave transmissive cover includes a cover body that is attached to the vehicle and covers the sensor device from a front side in an emission direction of the electromagnetic waves, and a seal member that provides a seal between the sensor device and the cover body. The seal member includes an attachment base portion that is attached to the cover body while surrounding the electromagnetic wave transmissive portion, and an annular hollow seal portion that is coupled to the attachment base portion and is in contact with the sensor device while surrounding the electromagnetic wave transmissive portion.

Electromagnetic wave transmissive cover and sensor module

A method for manufacturing a near-infrared sensor cover includes arranging a mask in a region of an undercoating layer formed on a rear surface of a base, the region being different from a heater formation region in which a heater is to be formed and different from a belt-shaped separation region extending along an edge of the heater formation region, forming a heat-generating film on the mask and the undercoating layer, the heat-generating film being made of the conductive heat-generating material, peeling, using a laser, the heat-generating film formed in the separation region, and removing the mask and the heat-generating film formed on the mask. The separation region has a width that is set to be smaller than a beam diameter of each of near-infrared rays transmitted from the transmitting portion.
