We describe the full X-ray source catalog from the Chandra Multi-wavelength Plane Survey (ChaMPlane). Taking advantage of the high sensitivity and superb spatial resolution of the Chandra X-ray Observatory, ChaMPlane constrains the distribution and nature of the faint Galactic X-ray sources. ChaMPlane uses the archival data of Chandra observations within 12 deg of the Galactic plane and not centered on bright sources or clusters. ChaMPlane also includes our own targeted observations such as the deep Bulge Window Survey and the shallow Bulge Latitude Survey. We have processed about 180 individual Chandra pointings for 74 separate fields from the Galactic Bulge to Anti-Galactic center region under a custom developed X-ray analysis pipeline. More than 15000 discrete X-ray sources have been found, with luminosity down to 1030-31 erg/sec (for D=8.5 kpc) in the deep exposure of Galactic center region fields. The catalog includes the astrometric and photometric results of each X-ray source along with energy quantiles, which allows a simple classification of faint X-ray sources with diverse spectral types. This catalog will be a legacy database for future study of Galactic X-ray sources, and it will complement the relatively bright source list in the Chandra Source Catalog and the XMM-Newton Galactic Plane Survey.
