摘要： A glass body (100) includes a first glass plate (1) having a first surface and a second surface (12) on an opposite side to the first surface. At least one plate surface of the first surface and the second surface (12) includes a radio wave transmission region (43) through which radio waves having a wavelength having linearity are allowed to be transmitted. The radio wave transmission region (43) includes a plurality of radio wave passage sections (43A) through which the radio waves are allowed to pass and which is spaced apart from each other, and a conductive film section (43B) in which a conductive film having a blocking property for the radio waves is formed between the radio wave passage sections (43A) adjacent to each other. The radio wave transmission region (43) is configured with a radio wave diffusion structure in which some of the radio waves that have passed through the plurality of radio wave passage sections (43A) are diffracted and overlap each other in a space facing the conductive film section (43B).
