<p>There is provided a fluid control apparatus which enables reducing widths of lines for further reducing space occupied by the apparatus. Support flow-channel blocks 9 and 10 are constituted by large block portions 25 and 27 which have openings of fluid flow channels 9a and 10a abutted against openings of fluid flow channels 11c and 11d in extended flow-channel blocks 11a and 11b with seal portions 20 interposed therebetween and, also, are abutted against lower surfaces of the extended flow-channel blocks 11a and 11b, and small block portions 26 and 28 which have lower surfaces flushed with the large block portions 25 and 27 and have heights smaller than those of the large block portions. The small block portions 26 and 28 are provided with male-screw-members insertion holes 26a and 28a for mounting the support flow-channel blocks 9 and 10 to a base member 30.</p> |
