PROBLEM TO BE SOLVED: To inspect electric continuity of boards to be taken in large numbers in a later process while a tape-like object wound in a roll state is reeled out and reeled in. SOLUTION: In this electric continuity checking device for a tape-like object X, whenever the tape-like object X is intermittently reeled out by a prescribed length by a reeling-out mechanism 12 and reeled in by a reeled-in mechanism 22, cameras 3, 4 respectively pick up images of front and rear reference points marked in a board area to be obtained in a later process (i.e., a punching process) together with the board area, and the picked-up images are analyzed to calculate coordinate data of the respective reference paints. The board area is intermittently fed to right under and right above a pair of upper and lower electric continuity checkers 5, 5, the calculated coordinate data is compared with coordinate data of reference points on front and rear surfaces of the electric continuity checkers 5, 5 taught in a memory part of a image processor 6 to calculate corrected data, a control part 7 controls the respective electric continuity checkers 5, 5 according to the corrected data to move them (in the X-axis direction, the Y-axis direction and theθdirection) and to move in the Z direction, and electric continuity of an electrode pattern in each the board area is checked.
