To surely reinforce a joining portion of a filter mesh while minimizing circulation resistance of a fuel, in a fuel filter configured by mold-joining a cylindrical filter mesh joined to a filter frame made of a synthetic resin and having several opening portion in a circumferential direction, one joining portion in the circumferential direction, and inserted and fixed to a fuel inlet cylinder of an electromagnetic fuel injection valve.
A filter frame 43 integrally has a cylindrical portion 43a, a disc-shaped end wall portion 43b disposed at an interval from the cylindrical portion 43a in an axial direction, and first and second connecting frame portions 43c, 43d connecting one end portion of the cylindrical portion 43a and the end wall portion 43b, and forming opening portions 45, 46 therebetween. The first connecting frame portion 43c in which the joining portion of the filter mesh 44 is buried and supported, has a width along a circumferential direction of the cylindrical portion 43a, larger than the second connecting frame portion 43d disposed on a position opposed to the first connecting frame portion 43c.
