A large-area X-ray gas detector includes a housing having an inner cavity and a ray entrance communicated with the inner cavity, a thin entrance window and a signal collection module. The inner cavity is filled with a working gas which is a non-electronegativity gas sensitive to the X-ray. The entrance window is hermetically connected to the ray entrance such that the X-ray enters into the inner cavity. The signal collection module comprises an anode wire electrode layer and a cathode electrode layer arranged parallel with each other in the inner cavity, in which the anode wire electrode layer has an anode wire for accessing to a high voltage, and the cathode electrode layer is grounded. The anode wire electrode layer collects electrons generated by the working gas under an action of the X-ray.
