Adhesive tape and substrate for adhesive tape

An adhesive tape comprising an adhesive layer on at least one surface of a substrate, wherein said substrate comprises an olefin polymer having a carbonylic oxygen atom in a molecular skeleton, a metal hydroxide surface-treated with a silane coupling agent, and a salicylic acid compound,

• wherein
• the content of said olefin polymer is 10-70% by weight relative to the whole weight of the polymer components constituting the substrate,
• the content of said metal hydroxide surface-treated with a silane coupling agent is 80-200 parts by weight relative to 100 parts by weight of the polymer components constituting the substrate, and
• the content of said salicylic acid compound is 0.05-10.0 parts by weight relative to 100 parts by weight of the polymer components constituting the substrate.

A substrate for an adhesive tape, which comprises an olefin polymer having a carbonylic oxygen atom in a molecular skeleton, an inorganometallic compound surface-treated with a silane coupling agent, a salicylic acid compound, and a flame-retarder,

• wherein
• the content of said olefin polymer is 10-70% by weight relative to the whole weight of the polymer components constituting the substrate,
• the content of said inorganometallic compound surface-treated with a silane coupling agent is 10-100 parts by weight relative to 100 parts by weight of the polymer components constituting the substrate,
• the content of said salicylic acid compound is 0.05-10.0 parts by weight relative to 100 parts by weight of the polymer components constituting the substrate, and
• the content of said flame-retarder is 10-100 parts by weight relative to 100 parts by weight of the polymer components constituting the substrate.
