PROBLEM TO BE SOLVED: To provide a line filter with reliability to a mechanical impact improved by providing a structure for stabilizing a fixing and holding of a core to a bobbin. SOLUTION: The line filter of this invention comprises: a first magnetic core 15; a bobbin 17 having a through-hole 14 with the first magnetic core 15 inserted; a second magnetic core 19 for covering a part of the first magnetic core 15, and a winding wound around the outer circumference of the bobbin 17. The bobbin 17 is formed with identically shaped two separated bobbins 17a, 17b separated in an axis direction of the through-hole 14 assembled. The second magnetic core 19 is formed by two separated magnetic cores 19a, 19b. The separated magnetic cores 19a, 19b are arranged in a groove for the magnetic core provided at the through-hole 14 side of the bobbin, and stoppers 20a, 20b for pressurizing the second magnetic core 19 are provided to one end part of the groove for the magnetic core.
