Inductor and voltage converter using it

An inductor comprising:

• an element assembly made of an electrical insulating material;
• a plurality of conductors disposed inside the element assembly and extending between a pair of end portions of the element assembly, each of the plurality of conductors is made of a flat-type wire having a rectangular cross section and includes a cylindrical winding section in which the flat-type wire in a longitudinal direction of the rectangular cross section is wound a number of turns less than one about a second direction intersecting with a first direction connecting the pair of end portions along the second direction, and the plurality of conductors are connected in parallel with each other;
• and
• a pair of outer electrodes disposed on the pair of end portions of the element assembly and electrically connected to end portions of the conductors.
