PROBLEM TO BE SOLVED: To provide a separator for an electric double-layer capacitor and the electric double-layer capacitor having superior durability with respect to a high-temperature atmosphere and fewer troubles in a handling process. SOLUTION: The electric double-layer capacitor uses a separator made of a polyimide porous film having a nonlinear fine hole and an electrolyte solution and a pair of polarization electrodes as components. The separator for the electric double-layer capacitor has a polyimide porous film as a component. In the polyimide porous film, an average void diameter ranges from 0.01 to 10μm, a void rate is 20 to 80%, a Gurley value is 50 to 1,000 second/100 ml, a film thickness ranges from 5 to 300μm, and the non-linear fine hole is provided.
