Internal jet structure in dijet production in deep-inelastic scattering
is measured with the H1 detector at HERA.
Jets with transverse energies $E_{T, {\rm Breit}} > 5$ \, GeV are
selected in the Breit frame employing $k_\perp$ and cone jet algorithms.
In the kinematic region of squared momentum transfers 
$10 < Q^2 \le 120$\, GeV$^2$ ~and $x$-Bjorken values  
$2 \cdot 10^{-4} \le x_{\rm Bj} \le 8 \cdot 10^{-3}$,
jet shapes and subjet multiplicities are measured as a function of 
a resolution parameter.
Distributions of both observables are corrected for detector effects 
and presented as functions of the transverse jet energy and jet 
pseudo-rapidity.
Dependences of the jet shape and the average number of subjets
on the transverse energy and the pseudo-rapidity of the jet are observed.
With increasing transverse jet energies and decreasing pseudo-rapidities,
i.e.\ towards the photon hemisphere, the jets are more collimated.
QCD models give a fair description of the data.
