PROBLEM TO BE SOLVED: To provide a multi-row type flexible tube which can suppress a reduction in a fluid flow rate at a curve and stay of the fluid, and the variation of an ink transfer amount between a plurality of channels, and to provide a fluid jetting apparatus using the same. SOLUTION: The ink supply tube 12 of an approximately belt shape includes a plurality of ink channels 101 arranged in parallel in a width direction, and further includes a pair of wide surfaces 102 in the parallel arrangement direction. The ink supply tube adopts such a configuration that the thickness of part where the ink channels 101a and 101d at width-direction both ends are formed is larger than the thickness of part where the other ink channels 101b and 101c are formed, and each cross section of the ink channels 101 has a shape longer in thickness direction than in width direction.
