PROBLEM TO BE SOLVED: To provide a method of forming a suction opening of a glass panel by which excellent airtightness is secured as the suction opening. SOLUTION: In the method of forming the suction opening of the glass panel by providing a through hole 3 on one plate glass A, erecting a glass pipe 7 for suction in the through hole 3, externally engaging an annular molding 8 for sealing with a base end part of the glass pipe 7, heating and melting the molding 8 for sealing to flow throughout the base end part of the glass pipe 7 and the throughhole peripheral part 1a of the one plate glass 1A and solidifying it to form a seal part S when the suction opening 6 for pressure-reducing and hermetically sealing an airtight gap part V between both plate glasses 1 is provided on any one plate glass 1A of a pair of the plate glasses 1 arranged with a certain interval in the thickness direction, an inclined surface K for introducing the heated and melted molding 8 for sealing around the glass pipe 7 is previously formed on the throughhole peripheral part 1a of one plate glass 1A.
