Inductor and manufacturing method therefor

A method for manufacturing an inductor, the method comprising:

• preparing a body of an anodic oxidation film material;
• forming vertical through parts, wherein a plurality of first vertical through parts is formed at a first side of the body and formed through upper and lower surfaces of the body and arranged in a column direction, and a plurality of second vertical through parts is formed at a second side of the body and formed through the upper and lower surfaces of the body and arranged in the column direction;
• forming vertical connection parts, wherein electrically conductive materials are filled into the plurality of first vertical through parts and the plurality of second vertical through parts to form a plurality of first vertical connection parts and a plurality of second vertical connection parts;
• forming horizontal connection parts, wherein a plurality of first horizontal connection parts is formed above the body and connect upper surfaces of the plurality of first vertical connection parts to upper surfaces of the plurality of second vertical connection parts, and a plurality of second horizontal connection parts is formed below the body and connect lower surfaces of the plurality of first vertical connection parts and lower surfaces of the plurality of second vertical connection parts;
• and
• forming a through hole, wherein the through hole is formed through the upper and lower surfaces of the body to be located inside the first and second vertical connection parts.
