PROBLEM TO BE SOLVED: To provide a multilayer inductor capable of suppressing reduction in a Q value caused by a skin effect even when a current of a high-frequency region flows in a coil. SOLUTION: A mounting face length per unit length of a conductive layer 2 is set to 1≤(mounting face length/unit length)≤1.3, and thereby the surface smoothness of the conductive layer 2 is enhanced to shorten the substantial surface length of the coil. Therefore, even when the current flows to be concentrated on the surface of the coil by the skin effect, a resistance value can be decreased to suppress the reduction in the Q value.
