[en] The internal jet structure in dijet production in deep-inelastic scattering is measured with the H1 detector at HERA. Jets with transverse energies E_T,Briet > 5 GeV are selected in the Breit frame employing k_{perpendicular} and cone jet algorithms in the kinematic region of squared momentum transfers of 10 < Q² < or approx. 120 GeV² and x-Bjorken values of 2 · 10^-4 < or approx. x_Bj < or approx. 8 · 10^-3. Jet shapes and subject multiplicities are measured as functions of a resolution parameter. The corrected data are well described by QCD models. It is observed that jets are more collimated with increasing transverse jet energies and decreasing pseudo-rapidities, i.e. towards the photon direction. Comparisons with OPAL data show that jet shapes of jets measured in γγ collisions are very similar to those measured in ep collisions
