摘要：
An electrostatic charge on a release sheet is prevented, and thus workability during paying out of a release sheet from a roll is improved.A release sheet 10 comprises a release sheet base 11, an undercoat layer 12 formed on the release sheet base 11, and a release agent layer 13 formed on the undercoat layer 12. The undercoat layer 12 contains a polyolefin-type antistatic agent with specific surface resistance (ASTM D 257) of less than or equal to 109Ω. The surface resistivity (JIS K 6911) of the release sheet 10 is less than or equal to 1014 Ω/square.
