To avoid a miss of a control program to be rewritten when changing a manifold power feed direction and avoid a malfunction caused thereby.

Connecting terminals A3-A14 and B1-B12 are provided in the left/right of respective manifold blocks 14, at least, solenoid valves 1a-7a and 1b-7b are deviated in an array direction by the value of the number and the left/right connecting terminals A3-A14 and B1-B12 are electrically connected to one another. Specific connecting terminals A1 and A2 non-connected by deviated in the array direction are provided on the left connecting terminal row A and specific connecting terminals B13 and B14 non-connected by deviated in the array direction are provided on the right connecting terminal row B. The specified connecting terminals A1 and A2 falling under first by counting from the one end side of the connecting terminal row A out of the left specific connecting terminals A1 and A2 and the specific connecting terminals B14 and B13 falling under the first by counting from the other end side of the connecting terminal row B out of the right specific connecting terminals B13 and B14 are connected together.
