Abstract: Provided are a resin molded component, a method for producing the resin molded component, and a method for producing a welded resin-molded article which ensure appropriate welding at a portion to be welded, without causing insufficient strength. A resin molded component 1 includes a body portion 10 and a rib 11 integrally molded with each other, the rib 11 protruding from the body portion 10 and configured to be infrared welded to a predetermined resin component 2, the resin molded component 1 having a foamed layer 12 formed at least in the body portion 10. A leading end portion of the rib 11 of the resin molded component 1 has a thinned remainder 11b which has been thinned relative to a root portion of the rib. For example, the rib width of the thinned remainder 11b of the rib 11 is smaller than the rib width of the root portion.

Abstract: An electromagnetic wave transmissive cover includes: a base made of a dielectric material and having transmissiveness to electromagnetic waves; and a reflection hindering layer laminated on at least one of two surfaces of the base in a travel direction of the electromagnetic waves, made of a dielectric material, having transmissiveness to the electromagnetic waves, and hindering reflection of the electromagnetic waves. A wavelength of each electromagnetic wave in the reflection hindering laver is referred to as λ2 and 2π/λ2 is set as a phase constant β2. An amount of deviation between a phase of a reflected wave reflected on the front interface of the reflection hindering layer in the travel direction and a phase of a reflected wave reflected on the rear interface is referred to as a phase deviation amount β. Thickness L2 of the reflection hindering layer is set to β/β2.

Abstract: A radio wave transmissive cover includes a conductive thin film. The conductive thin film includes unit thin film sections each including a hole region, a conduction region, and a patch region. Expressions 1 to 3 hold among a radius r of the patch region, a minimum dimension c of the conduction region, a width w of the hole region, a frequency frmin, frequencies f1, f2, and an index value Q. frmin = - 91  r - 7.2  c + 11.8  w + 113.5 ( Expression   1 ) Q = Kr  f   1 - f   2  ( Expression   2 ) Q = 79  r - 2.4  c + 23  w - 38.6 ( Expression   3 ) The radius r, the minimum dimension c, and the width w are determined based on Expressions 1 to 3 such that the frequency frmin is in a range from 70 GHz to 80 GHz and that the index value Q is in a range from −15 to −5.
