Decorative sheet, and transparent resin sheet

A decorative sheet comprising:

• a transparent resin layer containing a crystalline polypropylene resin as a main component,
• a nano-sized nucleating agent contained in the transparent resin layer,
• the nano-sized nucleating agent is contained in the transparent resin layer in a state where the nucleating agent is encapsulated in a vesicle having a monolayer outer membrane,
• wherein
• a value of a peak area ratio x represented by a following expression (1) of the transparent resin layer is x≥0.4,
• S040, S130 and Sam in the following expression (1) are peak areas calculated from an X-ray diffraction spectrum obtained by measuring the transparent resin layer by an X-ray diffractometer using Cu for an X-ray source, S040 represents a peak area from a Miller index (040) of polypropylene α crystals, S130 represents a peak area from a Miller index (130) of the polypropylene α crystals, and Sam represents a peak area of an amorphous material,
