    摘要： A spacer of the present disclosure is interposed between a first glass substrate and a second glass substrate opposing each other, and is disposed in contact with the first glass substrate and the second glass substrate. The spacer of the present disclosure includes a first contact surface disposed in contact with the first glass substrate, a second contact surface disposed in contact with the second glass substrate, and a side surface positioned between the first contact surface and the second contact surface. A mean value RΔq 1 of a root-mean-square slope in a roughness curve of the first contact surface is smaller than a mean value RΔq2 of a root-mean-square slope in a roughness curve of the side surface.

    摘要： A depressurized multilayered glass panel includes: a pair of opposing glass plates 1A, 1B; a plurality of space holding members arranged in a gap formed between the pair of glass plates 1A, 1B; a peripheral edge sealing material 11 configured to seal a gap of a peripheral edge 3 of the pair of glass plates 1A, 1B; and a suction hole sealing material 15 configured to seal a suction hole 4 penetrating through the front and the back in one of the pair of glass plates 1A, 1B in a state where the gap is depressurized via the suction hole 4, in which the center of the suction hole 4 is provided at a position away from an edge 3A of the pair of glass plates 1A, 1B by 10 mm or more and 100 mm or less and the upper limit of the weight of the suction hole sealing material 15 is calculated according to a mathematical equation.
