11 (Inlet manifold groove 11A and outlet manifold groove
11B), a gradient is provided from the starting point on the inlet gas hole 5A side or the outlet gas hole 5B side to the end point on the farthest gas distribution groove 7B side. This gradient is such that the depth at the start point is the deepest and the depth at the end points on both sides is the shallowest.

溝7に均一にガスA,Bが流れる。By providing such a gradient, the groove width of the manifold groove 11 is constant and the groove depth becomes shallower in the flow direction of the gases A and B. Pressure loss is proportional to the square of the gas flow rate, and the gas flow rate is proportional to the cross-sectional area if the flow rate is constant. Therefore, the flow rate decreases in the direction in which the cross-sectional area decreases (gas flow direction). Also in the case where no gradient is provided (conventional product), the gas A and B are branched by the gas distribution groove 7 in the gas flow direction, and the gas flow rate decreases. The gas distribution groove 7 closer to the 5A side or the outlet gas hole 5B had a lower flow rate. By providing a gradient, the inlet gas holes 5
By making it difficult for the gases A and B to flow into the gas distribution groove 7 farther than the A side or the outlet gas hole 5B, the gases A and B are conveyed to the gas distribution groove 7 closer to the inlet gas hole 5A or the outlet gas hole 5B. B easily flows, and the gases A and B flow uniformly in the gas distribution groove 7 in total.
