PROBLEM TO BE SOLVED: To provide a hybrid type X-ray detector capable of high-quality imaging and an X-ray CT apparatus provided with such an X-ray detector. SOLUTION: The X-ray detector includes two or more columns of detection signals and reference channels for respective columns. The detection channels comprise two or more groups of detection channels (510a, 520a) for which the product of the number of columns and the pitch of the columns is equal and the combination of the number of columns and the pitch of the columns is different. The reference channels comprise two or more groups of reference channels (510b, 520b) for which the combination of the number of columns and the pitch of the columns matches with the combination of the number of columns and the pitch of the columns respectively in the two or more groups of detection channels.
