1. A resonator comprising:
- a magnetic core including a first magnetic core block and a second magnetic core block, the second magnetic core block being disposed at an interval from the first magnetic core block; and
a coil wound on the magnetic core in a lateral direction of the first and second magnetic core blocks,wherein the first magnetic core block includes a first portion and second portions on sides of the first portion along a longitudinal direction of the first magnetic core block, and a sectional area of the first portion is larger than each sectional area of the second portions in a direction orthogonal to the longitudinal direction of the first magnetic core block,wherein the second magnetic core block includes a third portion and fourth portions on sides of the third portion along the longitudinal direction of the second magnetic core block, and a sectional area of the third portion is larger than each sectional area of the fourth portions in a direction orthogonal to the longitudinal direction of the second magnetic core block, andwherein the coil is wound on the first portion of the first magnetic core block and the third portion of the second magnetic core block.
