A noise suppressing connector comprises a shielding casing, first and second contact pins to be connected to external circuits, and a filter including at least one capacitor and a coil wound about a core made of a ferromagnetic material. An insulative housing is enclosed by the casing, and this insulative housing has a partition defining a bore with the inner wall of the housing. The first contact pin passes through the partition to project into the bore, while the filter is disposed in the bore to be connected between the first and second contact pins. At least one conductive plate is disposed in the bore and is connected to the casing for effectively shielding the filter and for serving as a ground circuit. The space in the bore may be filled with a suitable insulative material. The number of capacitors and coils may be increased to constitute a desired filter, such as a low-pass, high-pass or band-pass filter. With this provision noises which tend to pass through the connector are blocked, while induction and radiation of interfering waves and spurious waves are effectively prevented.
