PROBLEM TO BE SOLVED: To provide a structure capable of being easily manufactured and equipped with a fine flow channel of high reliability, a liquid droplet discharge head, and a microarray manufacturing apparatus. SOLUTION: The structure is equipped with a first member 100 having a plurality of first fine flow channels 122, which each keep one end opened, provided to one side 124 thereof, a second member 200 having a plurality of second fine flow channels 212 respectively opened at the positions almost corresponding to the openings 50 of a plurality of the first fine flow channels 122 of the surface opposed to one side 124 of the first member 100 and the packing member 300 interposed between the first and second members 100 and 200. The packing member 300 has a plurality of through-holes 39 extending in the thickness direction of the packing member 300 to be parallely provided so as to leave a partition wall to connect the first and second fine flow channels 122 and 212. The hole diameter of each of the through-holes is smaller than the narrow distance of the most approach distance between the mutual outer edges of the adjacent openings of the first fine flow channel and the most approach distance between the mutual outer edges of the adjacent openings of the second fine flow channel.
