Abstract The cross section for inclusive jet production in diffractive deep-inelastic scattering is presented. The leading final state proton is detected in the H1 Forward Proton Spectrometer. The data have been collected during the HERA-2 period and correspond to an integrated luminosity of 156.7 ${\rm pb}^{-1}$. The data cover the range $x_{IP} <0.1$ in fractional proton longitudinal momentum loss, $|t| \leq 1.0~{\rm GeV}^2$ in squared four-momentum transfer at the proton vertex and $4 \leq Q^2 \leq 110~{\rm GeV}^2$ in photon virtuality. The dijet topology is defined by two inclusive jets in the central region, found by the $k_T$ cluster algorithm in the hadronic centre-of-mass system. The presented cross sections are corrected to the level of stable hadrons and compared to the Monte Carlo generator level predicitons and NLO predictions with applied hadronization corections.
