A noise filter includes: a capacitor-side accommodating body including capacitors, a grounding conductor connected to one electric connector, and conductors connected to the other electric connector; an inductor-side accommodating body including inductors and conductors connected to the inductors; an accommodating body connecting structure that connects the capacitor-side accommodating body to the inductor-side accommodating body by engaging a holding groove with a protrusion; a terminal connecting structure that electrically connects the capacitors to the inductors, and connects the capacitor-side accommodating body to the inductor-side accommodating body by connecting one terminal connector of a connection terminal fitting to a terminal connector of a capacitor-side conductor, and connecting the other terminal connector of the connection terminal fitting to a terminal connector of an inductor-side conductor.
