An oil strainer is provided with a tube (41) for allowing oil to flow therethrough, a mesh (71) mounted to one end (41m) of the tube (41), a protector (61) connected to said end (41m) of the tube (41) so as to cover the mesh (71), and a bracket (51) for fixing the tube (41) to a surrounding member mounted around the oil strainer (31). The bracket (51) has a staking section (53) for staking the protector (61) and the tube (41) together. The above structure enhances productivity of the oil strainer and reduces costs of the oil strainer.
