Claim Text:
1. A flow rate control device comprising a basal plate block having a substantially rectangular mounting surface including short sides and long sides, wherein the short sides are shorter than the long sides; a single input port into which a fluid flows, wherein the single input port opens on an outer surface of the basal plate block; a single output port from which the fluid flows out, wherein the single output port opens on the outer surface of the basal plate block; two inflow channels whose proximal ends are connected to the input port, wherein the two inflow channels are formed inside of the basal plate block; two outflow channels whose terminal ends are connected to the output port, wherein the two outflow channels are formed inside of the basal plate block; and two flow rate control units arranged on the substantially rectangular mounting surface of the basal plate block, wherein each of the two flow rate control units comprises: one of the flow rate control units is arranged between one of the inflow channels and one of the outflow channels, the other flow rate control unit is arranged between the other inflow channel and the other outflow channel, and each of the flow rate control units is configured to be capable of operating independently to control a flow rate, and as viewed from a direction perpendicular to the mounting surface, each of the two inflow channels diagonally leads from the single input port toward either long side of the mounting surface and each of the two outflow channels diagonally leads from the either long side of the mounting surface to the single output port.
