  The $g$-component edge connectivity $c\lambda_g(G)$ of a non-complete graph
$G$ is the minimum number of edges whose deletion results in a graph with at
least $g$ components. In this paper, we determine the component edge
connectivity of the folded hypercube
$c\lambda_{g+1}(FQ_{n})=(n+1)g-(\sum\limits_{i=0}^{s}t_i2^{t_i-1}+\sum\limits_{i=0}^{s}
i\cdot 2^{t_i})$ for $g\leq 2^{[\frac{n+1}2]}$ and $n\geq 5$, where $g$ be a
positive integer and $g=\sum\limits_{i=0}^{s}2^{t_i}$ be the decomposition of
$g$ such that $t_0=[\log_{2}{g}],$ and
$t_i=[\log_2({g-\sum\limits_{r=0}^{i-1}2^{t_r}})]$ for $i\geq 1$.
