Noise filter and wire harness

A wire harness comprising:

• a trunk line including a first electric wire and a second electric wire;
• and
• a noise filter that reduces a noise component, wherein
• the noise filter includes
• a filter circuit including a noise reduction element that reduces the noise component, a conductive first circuit connection member to which a first connection portion of the noise reduction element is electrically connected, and a conductive second circuit connection member to which a second connection portion of the noise reduction element is electrically connected,
• a first electric connection structure that electrically connects an intermediate connection portion of a core wire of the first electric wire to the first circuit connection member, and
• a second electric connection structure that electrically connects an intermediate connection portion of a core wire of the second electric wire whose one end is grounded, to the second circuit connection member, wherein
• the first electric connection structure includes a first electric wire side connection body physically and electrically connected to the intermediate connection portion of the core wire of the first electric wire, and a first circuit side connection body physically and electrically connected to the first electric wire side connection body and the first circuit connection member, and
• the second electric connection structure includes a second electric wire side connection body physically and electrically connected to the intermediate connection portion of the core wire of the second electric wire, and a second circuit side connection body physically and electrically connected to the second electric wire side connection body and the second circuit connection member.
