Abstract

The present invention provides a novel antistatic sheet having high gas barrier performance, high water vapor barrier performance, and antistatic performance, and a packaging material and an electronic device that include the antistatic sheet. The present invention relates to an antistatic sheet including a multilayer structure including a base (X), a layer (Z) containing an aluminum atom, and a layer (Y). The layer (Y) contains a polymer (A) having a vinylphosphonic acid unit, and the layer (Y) has a surface electrical resistivity of 1.0×10Ω/sq or more and 4.0×10Ω/sq or less.
