Abstract

Disclosed are a separator (100) and an electrochemical device, specifically relating to the battery technology field. The separator (100) includes a porous base film (101), a heat-resistant layer (102) and an adhesive layer (103), wherein the heat-resistant layer (102) is disposed on at least one surface of the porous base film (101). The adhesive layer (103) is at least disposed on a surface of the heat-resistant layer (102) opposite to a surface in contact with the porous base film (101). An effective adhesion degree R-value of the separator (100) on a side where the heat-resistant layer (102) is provided is 40%-80%, and a difference between a maximum value and a minimum value of the effective adhesion degree R-value is <30%; wherein the effective adhesion degree R-value indicates a ratio of an effective adhesion area to a theoretical adhesion area of the separator (100).
