Inductor structure, circuit board and electronic device

An inductor structure, comprising:

• a magnetic core column, comprising a first part, a second part and a third part arranged sequentially along a first direction, the first direction being perpendicular to a length direction of the magnetic core column;
• a wire wound around the magnetic core column and-is configured to be electrically connected with the circuit board;
• wherein, the first part has a first side wall facing away from the second part, the third part has a second side wall facing away from the second part, and the first side wall and/or the second side wall is/are arranged in a curved shape;
• and the second part has a first cross-section perpendicular to the length direction of the magnetic core column, the first cross-section is rectangular;
• and a length and a width of the first cross-section meet a condition of:
• H/M∈(1.2, 1.8), wherein H is the length of the first cross-section, in mm;
• and M is the width of the first cross-section, in mm, the wire is a flat wire, the flat wire has a flat side, and the flat side is attached to the magnetic core column.
