PROBLEM TO BE SOLVED: To provide a radio wave transmission cover which maintains designability even when detachment occurs.SOLUTION: A radio wave transmission cover 10 includes a transparent member 20 and a substrate 40. The transparent member 20 has an end part 21 with a recessed portion 22, and is capable of transmitting radio waves or light. The substrate 40 has an end part 46 with a protrusive portion 42 engageable with the recessed portion 22, and is joint to the transparent member 20. Further, a first inclined portion 23 and a second inclined portion 24 are formed on the transparent member 20. The first inclined portion 23 inclines from an upper surface 26 or a lower surface 27 of the transparent member 20 toward an opposite side of the substrate 40. The second inclined portion 24 inclines from a terminal 28 of the first inclined portion 23 toward the opposite side of the substrate 40. Accordingly, light reflected on a joint surface 45 between the transparent member 20 and the substrate 40 is totally reflected inside of a transparent member front end face 25 and a detached section cannot be visually observed, even when detachment has occurred at the joint surface 45. Thus, the detached section is unnoticed and designability is maintained.SELECTED DRAWING: Figure 5
【課題】剥離が生じても、意匠性を保持する電波透過カバーを提供する。【解決手段】電波透過カバー10は、透明部材20および基材40を備える。透明部材20は、凹部22を端部21に有し、電波または光を透過可能である。基材40は、凹部22に係合可能な凸部42を端部46に有し、透明部材20に接合されている。また透明部材20は、第1傾斜部23および第2傾斜部24が形成されている。第1傾斜部23は、透明部材20の上面26または下面27から基材40とは反対側に向かって傾斜する。第2傾斜部24は、第1傾斜部23の末端28から基材40とは反対側に向かって傾斜する。これにより、透明部材20と基材40との接合面45で剥離が生じたとしても、接合面45で反射した光が透明部材前端面25の内側で全反射し、剥離した箇所が目視できない。したがって、剥離した箇所が目立たず、意匠性が保持される。【選択図】図5
