A photographic camera has a film cartridge chamber, a film take-up chamber, a film feed passage formed between a film window on a camera body and a pressure plate on a camera back and a film feed mechanism. A film cartridge in which a roll film is entirely rolled around a spool in a cartridge body to its leading end is loaded in the film cartridge chamber and the film is fed out through a film exit slit formed in the cartridge body by the film feed mechanism. A guide portion for leading the leading end of the film fed out through the film exit slit to the film feed passage is provided at the film cartridge chamber side end of the film feed passage. The guide portion includes at least an end guide surface provided on the camera body. A part of the guide portion including a corner portion between the end guide surface on the camera body and a surface of the camera body extending from the film window is formed of a smooth-faced gate member which is formed of a resin material containing therein no fiber, while the camera body is formed of a fiber-reinforced resin material.
