    摘要： Provided is a glass body in which a radio wave transmission region is inconspicuous in appearance and high performance due to a conductive film is capable of being maintained. A glass body includes a first glass plate configured to have a first surface and a second surface on an opposite side to the first surface. At least one plate surface of the first surface and the second surface includes a plurality of radio wave transmission regions (21) through which radio waves are allowed to be transmitted and which is spaced apart from each other, and a conductive film region (22) that is entirely coated with a conductive film (23) having a blocking property for the radio waves around the radio wave transmission regions (21). A patterning part (26) having a plurality of radio wave passage sections (24) through which radio waves are allowed to pass and which is spaced apart from each other, and a conductive film section (25) in which the conductive film (23) is formed between the radio wave passage sections (24) adjacent to each other is formed in each of the radio wave transmission regions (21).
