## Abstract

A gas adsorbent is placed on at least a surface of a first plate on one side in a thickness direction thereof or a surface of a second plate on one side in a thickness direction thereof. The gas adsorbent has a shape with relatively raised and lowered parts arranged alternately. The gas adsorbent is placed along a sealant that joins the first and second plates.

## Claims

### Claim 1

A method for producing an insulating glass unit, comprising:
as an adsorbent placing step, placing a gas adsorbent on at least a first surface of a first plate on one side in a thickness direction thereof or a second surface of a second plate on one side in a thickness direction thereof, the first plate being composed of at least a plate glass, the second plate being composed of at least a plate glass; and
as a joining step, hermetically joining the first surface of the first plate and the second surface of the second plate with a sealant intervening therebetween, wherein
the method comprises placing the gas adsorbent so as to have a shape with relatively raised and lowered parts arranged alternately by adjusting a moving speed of a means for placing the gas adsorbent, an application quantity of the gas adsorbent from the means, or an application speed of the gas adsorbent from the means at the adsorbent placing step,
the sealant comprises a peripheral part that has a frame shape, and a partitioning part that divides an inner space of the peripheral part, and
at the joining step, with the gas adsorbent having the shape placed on each of two sides between which the partitioning part intervenes, and with the gas adsorbent having the shape placed along the partitioning part, heat is supplied till the partitioning part is melted.

### Claim 2 (depends on 1)

The method of claim 1, wherein the shape is a wave shape with the relatively raised and lowered parts arranged alternately.

### Claim 3 (depends on 1)

A method of claim 1, comprising forming a gap between the gas adsorbent and the sealant at the joining step.

### Claim 4 (depends on 1)

A method of claim 1, comprising, at the adsorbent placing step, forming the gas adsorbent having the shape by dot printing.

### Claim 5 (depends on 4)

The method of claim 4, comprising, by the dot printing, linearly forming the gas adsorbent with a number of continuous parts each of which is in a shape of a dot, the continuous parts forming the raised parts.

### Claim 6 (depends on 1)

A method of claim 1, further comprising, as a second joining step, joining a third pane to one of a first pane formed from the first plate and a second pane formed from the second plate with a frame body intervening therebetween.

### Claim 7 (depends on 1)

A method for producing a glass window, comprising, as a setting-in step, setting an insulating glass unit produced by a method of claim 1 in a window frame.
