摘要： PROBLEM TO BE SOLVED: To provide a surface-mounting inductor capable of improving a Q value (disintegration energy) in a high-frequency band.
SOLUTION: A winding section 22c, on which a solenoidal-shaped coil 25 is wound, is inclined to two collar sections 22a and 22b, to which terminal electrodes 26a and 26b are formed respectively in a plan view. An angle of inclination θ is set within a range of 45 to 85°. Accordingly, a manetic flux ϕ generated by making a current flow through the coil 25 is crossed with the terminal electrodes 26a and 26b at the angle of inclination θ, and penetrated while being biassed to parts of the terminal electrodes 26a and 26b. The coil axis of the coil 25 runs parallel with the mounting surface 21a of the surface mounting type inductor 21, and is inclined to the terminal electrodes 26a and 26b in the plan view.
