Zusammenfassung:	PURPOSE:To constitute a subject filter as single parts, which are made into an array and molded in one chip, by using plural chip type capacitors for capacitors constituting respective noise filters, using ferrite powder mixed resin molds common to respective noise filters for ferrite and using a ground pattern for connecting plural chip type capacitors and ground. CONSTITUTION:The surface mounting noise filters are constituted as one kind of parts where the chip type capacitors 4 are respectively arranged on the ground pattern 2b and directly pinched by signal leads 1b so as to form a circuit including the capacitors 4, respective signal leads 1b and the capacitors 4 are made into the mold by the ferrite powder mixed resin mold 3, the filter circuits for the circuits of the number of necessary signal lines are made into the array and molded into one chip. Consequently, the ground patterns 2b can be incorporated in a shortest length, and a terminal for ground connection 2a is used to connect the capacitors 4 and ground at shortest even if the pattern is mounted to plural signal lines, whereby the occurrence of harmful inductance components can be prevented.
