PROBLEM TO BE SOLVED: To provide a surface mounted inductor wherein its each winding terminal is joined to each joining electrode without any folding, and in addition to this, the reliability of the fixation of its cores is improved. SOLUTION: In the surface mounted inductor wherein two pot-cores having umbilicuses and an air-core coil are stored, each pot-core having each umbilicus has in its inside a magnetic leg to be a winding core, and has terminal engaging recessed portions on a pair of opposite end surfaces present on its top surface, and further, has a pair of opposite notches in the skirts of its side surfaces. The air-core coil is a coil comprising a wound insulating coating wire having a fusing layer on its surface and is a so-called α-wound coil whose winding start and end terminals are derived respectively to the outer periphery of the winding. Also, there is provided each connecting terminal wherein its section is lateral-U-shaped, and an elasticity is given to it, and further, it sandwiches the terminal engaging recessed portions of the combined two pot-cores having umbilicuses, and moreover, it has a connecting portion extended from the middle of its one-hand end portion.
