Inductor and dc-dc converter

An inductor comprising:

• an element body formed by including a resin;
• a first coil conductor disposed in the element body;
• a second coil conductor disposed in the element body;
• a first terminal connected to the first coil conductor and exposed from a surface on one side in a first direction of the element body;
• a second terminal connected to the first coil conductor and exposed from the surface on the one side;
• a third terminal connected to the second coil conductor and exposed from the surface on the one side;
• and
• a fourth terminal connected to the second coil conductor and exposed from the surface on the one side,
• wherein the first terminal and the second terminal are disposed apart from each other in a second direction orthogonal to the first direction,
• the third terminal and the fourth terminal are disposed apart from each other in the second direction,
• the surface on the one side has a first region, a second region and a third region, the second region and the third region protruding further out from the element body in the first direction than the first region,
• the first region is provided between the second region and the third region in a third direction orthogonal to the first direction and the second direction,
• the first terminal is disposed in the second region, and
• the third terminal is disposed in the third region.
