1. A noise filter, comprising:
a non-divided type magnetic core in which a through-hole having a first opening and a second opening at respective ends of the through-hole is formed;
a conductive coupling terminal including a first connection portion and a second connection portion at respective ends of the conductive coupling terminal, the first connection portion and the second connection portion being connectable to busbars, the conductive coupling terminal being disposed inside the through-hole; and
a holding portion that holds the conductive coupling terminal disposed inside the through-hole, wherein
the conductive coupling terminal is held to the magnetic core by the holding portion in a state where the first connection portion faces the first opening from inside of the through-hole and the second connection portion faces the second opening from inside of the through-hole.
