PROBLEM TO BE SOLVED: To prevent electric-field coupling between capacitors and improve the characteristics of a noise filter device.SOLUTION: A noise filter device includes: a ground connection terminal 21 for grounding; a coil 31 around which a conductor wire 33 is wound; a pair of capacitors 41 constituting a &pgr;-type filter circuit C with the coil 31 and electrically connected to the ground connection terminal 21; and a housing 11 capable of housing the coil 31 and the pair of capacitors 41. The pair of capacitors 41 are disposed on one surface side with respect to a virtual plane dividing the coil 31 in half in the axial direction, and a conductive shield plate 24B grounded to the ground connection terminal 21 is interposed between the capacitors 41. |
