Abstract:

The present disclosure addresses the problem of providing: a glass panel unit having a getter material capable of exhibiting adsorption performance in a low-pressure area; and a getter material. A glass panel unit 10 comprises a first glass plate 20, a second glass plate 30 that faces the first glass plate 20, a frame body 40, a pressure-reduced space 50 and a gas adsorbent 60. The frame body 40 joins the first glass plate 20 and the second glass plate 30 to each other in an air-tight manner. The pressure-reduced space 50 is enclosed by the first glass plate 20, the second glass plate 30 and the frame body 40. The gas adsorbent 60 is arranged in the pressure-reduced space 50. The gas adsorbent 60 comprises a getter material. The getter material contains a plurality of grains composed of zeolite crystals. Each of grains making up more than half of the total weight of the plurality of grains has a diameter of 200 nm or more. The temperature at which the grains can be activated is 400℃ or lower.
