WIPO Patent Application WO/2023/032535
Kind Code:
A1
Abstract:
Provided is a glass body in which a radio wave transmission region is inconspicuous in appearance and by which the performance by a conductive film can be maintained at a high level. This glass body comprises a first glass plate having a first surface and a second surface on the opposite side to the first surface. A plate surface of at least one of the first surface and the second surface includes: a plurality of radio wave transmission regions (21) through which radio waves can be transmitted and which are spaced apart from each other; and conductive film regions (22) which are entirely coated with conductive films (23) having a property of blocking radio waves at the circumferences of the radio wave transmission regions (21). Each of the radio wave transmission regions (21) has formed therein a patterning part (26) having: a plurality of radio wave passage sections (24) which are spaced apart from each other and through which radio waves can be transmitted; and a conductive film section (25) in which a conductive film (23) is formed between two adjacent radio wave passage sections (24).
