[Problem] Provided is a method for producing a glass unit by which a glass plate is securely waterproofed even when, for instance, the glass plate has a relatively large surface area. [Solving Means]Provided is a method for producing a glass unit. The method comprises a step (A) of obtaining a glass plate comprising a glass substrate and a Low-E layer placed on the glass substrate; a step (B) ofapplying a protective sheet to the Low-E layer surface of the glass plate; an optional step (C) of subjecting the glass plate to at least one process selected from the group consisting of transportation, storage, processing, washing and handling; a step (D) of removing the protective sheet from the glass plate; and a step (E) of assembling a glass unit using the glass plate. The protective sheet comprises a waterproof layer, and a PSA layer provided to at least one face of the waterproof layer. The PSA layer has a surface hardness of 0.5 MPa or less. 提供一种玻璃单元的制造方法，通过该方法，即使在玻璃板具有相对大的表面积时玻璃板也牢固防水。提供一种玻璃单元的制造方法。该方法包括获得玻璃板
