Simple Explanation of Capacitor ESR | DigiKey

Equivalent series resistance (ESR) (represented by R esr in Figure 1) describes losses associated with moving charge through a capacitor. The resistance of the electrode and lead materials is a contributing factor, and losses occurring within the dielectric material itself also occur and are often dominant.
