PROBLEM TO BE SOLVED: To provide a fluid control valve including a valve body with a structure devised to avoid generation of a weld line in a seal surface without using a special mold structure.SOLUTION: The fluid control valve includes: a resin valve body 1 having a valve chamber 15 communicating with an inlet port 11 and an outlet port 12 formed in opposite side surfaces and opening at an upper surface center, and a valve seat 161 provided in an inner wall 16 of the valve chamber; a valve element 4 movable into or out of contact with the valve seat; and a valve upper body 2 having a drive part to drive the valve element. An inflow passage 13 is formed in a substantially L shape passing through the inner wall to communicate between the inlet port and the valve chamber via the valve seat. The inner wall is formed into a cylindrical body having a thick portion 163 to have a wall thickness thicker on the inlet port side than on the outlet port side. The valve body is provided, at a center of a lower surface, with a resin injected part 191. |
