Fluid control device

A fluid control device comprising a plurality of lines arranged in parallel and having respective inlets, as well as respective outlets, facing toward the same direction, each of the lines comprising a plurality of fluid controllers arranged in an upper stage and a plurality of coupling members arranged in a lower stage, specified lines among said lines having fluid channels thereof interconnected by line interconnecting means,

• the fluid control device being characterized in that the line interconnecting means comprises lower channel blocks each having a line interconnecting channel and arranged in upper stage of the specified lines interconnected, at the same position with respect to the direction of the lines, the line interconnecting channel having at least one upward opening, and at least one upper channel block disposed on an upper side of the lower channel blocks of adjacent lines interconnected and having a transverse channel extending orthogonal to the lines and downward channels extending from the transverse channel and communicating with the upward openings of the respective line interconnecting channels of the lower channel blocks, each of the lower channel blocks being removably fastened to the coupling member in the lower stage with screws from above, the upper channel block being removably fastened to the lower channel blocks with screws from above.
