Abstract: In an embodiment, an electronic component includes: an element body part 10 constituted by an insulative body of rectangular solid shape; an internal conductor 30 provided inside the element body part 10; and external electrodes 50 provided at least on the bottom face 14 (mounting surface) of the element body part 10 and electrically connected to the internal conductor 30; wherein the element body part 10 has: a conductor-containing layer 20 in which a coil conductor 36 (functional part) that will become a part of the internal conductor 30 to demonstrate electrical performance, is provided; and a high-hardness layer 22 which is provided side by side with the conductor-containing layer 20 in a direction parallel with the bottom face 14 (mounting surface) of the element body part 10, and which has a higher hardness compared to the conductor-containing layer 20. The electronic component has improve mechanical strength.
