We present the X-ray source catalog in the Subaru/XMM-Newton deep survey. A continuous area of 1.14 deg² centered at R.A.=02^h18^m and decl.=-05° is mapped by seven pointings with XMM-Newton covering the 0.2-10 keV band. From the combined images of the EPIC pn and MOS cameras, we detect 866, 1114, 645, and 136 sources with sensitivity limits of 6x10^–16, 8x10^–16, 3x10^–15, and 5x10^–15 ergs/cm2/s in the 0.5-2, 0.5-4.5, 2-10, and 4.5-10 keV bands, respectively, with detection likelihood ≥7 (corresponding to a confidence level of 99.91%). The catalog consists of 1245 sources in total including 32 extended-source candidates. The averaged logN-logS relations are in good agreement with previous results, bridging the flux range between Chandra deep surveys and brighter surveys. The logN-logS relations show significant spatial variation among pointings on a scale of 0.2 deg². Analyzing the autocorrelation function, we detect significant clustering signals from the 0.5-2 keV band sample, which can be fit with a power-law form (θ/θ_c)^–0.8 with a correlation length of θ_c=5.9^+1.0_–0.9 arcsec when the integral constraint term is included. In the 2-10 keV band, however, the clustering is not significant with a 90% upper limit of θ_c<1.5".
