Zusammenfassung:PROBLEM TO BE SOLVED: To provide a device having a good durability for high temperature. SOLUTION: A surface-mount device 1 includes a package 8 in which a circuit board 2 and a plurality of circuit elements 3 mounted on the circuit board 2 are sealed by a mold resin 5. An inductor 10 contained in the circuit element 3 of the device 1 includes a magnetic molded body 11 and a coil 15 contained in the magnetic molded body 11. The magnetic molded body 11 includes a mounting surface (lower surface) 11b facing the circuit board 2, a surface (upper surface) 11a opposite to the mounting surface, and a first inclined surface 51 surrounding the upper surface 11a and slanted to recede from the upper surface 11a.
