Object: A plurality of problems of an electromagnetic wave transmissive cover to be installed in an electromagnetic wave irradiation direction of a sensor using an electromagnetic wave are simultaneously eliminated. Resolution means: An electromagnetic wave transmissive coveris a member to be installed in an electromagnetic wave irradiation direction of a millimeter wave radarusing an electromagnetic wave, and includes a colored resin member, a transparent resin member, and a transparent heater film. The transparent resin memberis provided on an opposite side to the millimeter wave radarof the colored resin member. The transparent heater filmis provided on the opposite side to the millimeter wave radarof the colored resin member, includes a wiring pattern formed by copper plating or etching, and has electromagnetic wave transmissivity.

Electromagnetic wave transmissive cover and method for manufacturing the same

Provided is a decorative sheet in which a graphic is less deteriorated even after injection molding. First and second graphic layers contain a plurality of interference pigments that emit respective interference lights having respective colors in a first direction in first and second binders to exhibit first and second mixed colors. An optical functional layer changes a reflectance property of light. The first and second graphic layers represent a graphic visually recognizable from a front surface of a decorative sheet and allow visually recognizing an image displayed on a back surface from the front surface. The optical functional layer increases at least one of ratios of an amount of visible light representing the graphic and an amount of visible light representing the image that transmits through the first and second graphic layers to an amount of visible light reflected by and visible on the front surface.

A method for manufacturing a membrane switch member that can be manufactured easily and that can be caused to function as an electrostatic sensor even when a protruding portion is pressed. Injection molding by injecting a material including a supercritical fluid gas and a resin material in a mixed state; and, after the injection molding, removing a first mold from a second mold, causing gas produced within the injection molded resin to grow in concave portions, thereby causing the concave portions to invert to a protruding state; and manufacturing a membrane switch member in which voids are formed between the protruding portions and a molding resin layer, and portions other than the portions corresponding to the protruding portions are adhered to the resin layer by an adhesion layer.

Production method for a membrane switch member

In the simultaneous molding and decorating method for forming an image onto the surface of a resin molding simultaneously with resin molding by holding a decoration sheet on which the image is rotary printed in a die, such a decoration sheet as having a predetermined pattern for every revolution of the cylinder of a printing machine wherein the image is formed in the longitudinal direction at a constant interval is used. By holding the decoration sheet longer than one revolution but shorter than two revolutions of that in the die and performing resin molding, the image is formed onto the surface of a long molding exceeding the outer circumference of the cylinder.
