PROBLEM TO BE SOLVED: To provide a glass panel expectable to reinforce a sealing part and readily maintaining a sealing effect. SOLUTION: This glass panel is obtained by arranging a pair of plate glass 1 at a gap in the thickness direction and forming a glass panel main body P1 in which a cavity part V between both a pair of the plate glass is retained in a reduced pressure and closed through a suction hole 6 formed on one plate glass 1A of a pair of the plate glass. In constituting the suction hole 6, one plate glass 1A is provided with a through-hole 1a, a sucking gas tube 7 is stood on the through-hole 1a, a sealing part S of a low-melting glass is formed from the base end part of the glass tube 7 to the peripheral part of the through-hole 1a of one plate glass A. The tip part of the glass tube 7 is heated and melted and closed to give a closed part H. In this case, the coefficient of thermal expansion of a low-melting glass constituting a first sealing part corresponding to one plate glass 1A in the sealing part is set lower than that of one plate glass 1A.
