Provided is a filling-bonding material having a shape with an uneven thickness.

Provided is laminated glass and a preparation method thereof, an electronic device housing, and an electronic device. The laminated glass comprises at least two glass members and at least one adhesive film disposed in a stacked manner, where the glass members and the adhesive film are alternately disposed, wherein decorative layers are provided on surfaces of at least two of the glass members facing toward the adhesive film, and at least two of the decorative layers independently comprise at least one of an etched texture, an optical coating layer, and a pattern layer.

Provided is a sleeping bag including a warmth-improving portion. The warmth-improving portion includes a first insulation layer located on one surface in an inward direction of a sleeping bag outer covering and configured to block an inflow of the cold from the outside, a first compressed fiber layer located on one surface of the first insulation layer, and a heat-retention layer located on one surface of the first compressed fiber layer. According to the present invention, since it is possible to block the cold from the outside and to prevent warmth inside from being released using a first insulation layer, heat-retaining performance may be maximized. Since heat is generated on the basis of steam outside and inside a sleeping bag using a heat-retention layer, it is possible to easily increase and maintain a temperature inside the sleeping bag without a separate heat source.
