Method for producing insulating glass unit and method for producing glass window

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.
