Electric flux density is the measure of the intensity of an electric field inside a substance $S$.

It is defined as:

$\mathbf D = \varepsilon_0 \varepsilon_r \mathbf E$

where:

$\mathbf E$ denotes the electric field strength at a given point within $S$

$\varepsilon_0$ denotes the vacuum permittivity

$\varepsilon_r$ denotes the relative permittivity of $S$

Electric flux density is a vector quantity.
