We construct an X-ray spectral model from a clumpy torus in an AGN, designated as "XCLUMPY", utilizing the Monte Carlo simulation for astrophysics and cosmology (MONACO: Odaka et al. 2016). The adopted geometry of the torus is the same as that in Nenkova et al. (2008), which assumed a power law distribution of clumps in the radial direction and a normal distribution in the elevation direction. We investigate the dependence of the X-ray continuum and Fe Ka emission line profile on the torus parameters. Our model is compared with other torus models: MYTorus model (Murphy et al. 2009), Ikeda torus model (Ikeda et al. 2009), and CTorus model (Liu et al. 2014). As an example, we also present the results applied to the broadband X-ray spectrum of the Circinus galaxy observed with XMM-Newton, Suzaku, and NuSTAR. Our model can well reproduce the observed X-ray spectra. We compare our results with those obtained from other-wavelength observations.
