A glass panel unit includes: a first substrate including a first glass panel; a second substrate including a second glass panel; and a frame-shaped sealing portion that is hermetically bonded to the first substrate and the second substrate. The sealing portion creates an evacuated space between the first substrate and the second substrate. When viewed from a region where the second substrate is positioned with respect to the first substrate, the first substrate includes a part arranged to stick out of an edge of the second substrate. The part includes a mounting portion used to mount the glass panel unit onto a vehicle.

Laminated glass for a vehicle includes a vehicle-interior side glass plate, a vehicle-exterior side glass plate, an interlayer film that bonds the vehicle-interior side glass plate and the vehicle-exterior side glass plate, and a structure sealed in the interlayer film. The interlayer film includes a first interlayer film bonded to the vehicle-interior side glass plate, a second interlayer film bonded to the vehicle-exterior side glass plate, and a third interlayer film located between the first interlayer film and the second interlayer film to enclose an outer periphery of the structure. Where a film thickness of the first interlayer film or the second interlayer film, whichever is thinner, is denoted as ti, and a thickness of the structure is denoted as ts, ti/ts≥0.4 is satisfied. Where a flexural modulus of the structure is denoted as E.sub.1 [MPa], a relationship between ts and E.sub.1 satisfies E.sub.1×ts.sup.3≥500.
