Abstract: A fluid control valve includes: a resin valve main body including inlet and outlet ports in opposite side surfaces, a valve chamber communicating between the inlet and outlet ports and opening at the upper surface center of the main body, and a valve seat provided in an inner wall of the chamber; a valve element movable into or out of contact with the valve seat; and a valve upper body including a drive part to drive the valve element. An inflow passage is formed like an L shape extending through the inner wall to communicate between the inlet port and the chamber via the valve seat. The inner wall is cylindrical having a thick-wall portion to have a wall thickness thicker on the inlet port side than on the outlet port side. The valve main body is provided, at a center of a lower surface, with a resin injected part.
