A multilayer coil component includes an element body having a multilayer structure including a first element body portion formed of a ferrite element body material, and a second element body portion laminated on the first element body portion and formed of a ferrite element body material having a composition different from the ferrite element body material forming the first element body portion, a multilayer coil having an axis parallel to a lamination direction of the element body, and a stress alleviation portion provided in an inner region of the multilayer coil when viewed from the lamination direction. In the multilayer coil component, the stress alleviation portion is provided in the inner region of the multilayer coil in which a stress tends to be concentrated to alleviate the stress in the inner region of the multilayer coil, and thereby occurrence of cracking in the element body can be suppressed.
