Abstract An electronic device such as a vacuum fluorescent display tube for simply fixing simple-structure ringless getters and increasing a degree of freedom in disposing ringless getters. Ringless getters (G11-G13) are fixed to the inner surface of a glass anode substrate (111) by a laser beam. A laser beam, applied to ringless getters (G11-G13) from the outer side of the anode substrate (111), passes through the anode substrate (111) and heats and melts the getters (G11-G13), the inner surface of the substrate (111) being melted by the heating. Since the molten portions of the getters (G11-G13) and the substrate (111) solidify when left cooled, the getters (G11-G13) are fixed to the substrate (111). Ringless getters (G11-G13) are obtained by press-forming a getter material into an arbitrary shape. La présente invention concerne un dispositif électronique tel qu'un tube d'affichage électroluminescent permettant de fixer simplement des getters sans bague à structure monobloc et d'accroître un degré de liberté lors de la mise en place des getters sans bague. Les getters sans bague (G11-G13) sont fixés sur la surface interne d'un substrat d'anode en verre (111) par un faisceau laser. Ce faisceau laser, appliqué sur les getters sans bague (G11-G13) depuis le côté extérieur du substrat d'anode (111) traverse le substrat d'anode (111), puis chauffe et mélange les getters (G11-G13), la surface interne du substrat (111) étant fondue par la chaleur. Etant donné que les parties fondues des getters (G11-G13) et du substrat (111) se solidifient lorsqu'on les laisse refroidir, les getters (G11-G13) sont alors fixés au substrat (111). Les getters sans bague (G11-G13) sont produits par formage à la presse d'un matériau de getter sous une forme arbitraire.
