PROBLEM TO BE SOLVED: To provide a small-size fluoroscopic imaging apparatus capable of collecting X-ray images of different X-ray dose rates such as fluoroscopy and imaging and producing less image distortion. SOLUTION: This fluoroscopic imaging apparatus is provided with an X-ray source 2 irradiating the X-ray to a subject 1, a micro channel plate(MCP) type planar electron multiplier 3 disposed opposite to the X-ray source 2, converting the X-ray transmitting through the subject 1 into electrons and multiplying them, an X-ray plane detector 5 detecting the multiplied electron quantity as the X-ray image, a CRT(cathode-ray tube) monitor displaying the detected X-ray image, and an X-ray control device 7 multiplying the MCP type planar electron multiplier 3 according to a multiplication constant of the MCP type planar electron multiplier 3, when either of fluoroscopy or imaging is set as the condition of obtaining the X-ray image and the condition is for fluoroscopy or photographing.
