In a planar coil element, since an overlapping portion of a fourth resin wall of a first conductor pattern protrudes from an end surface of a main body portion, restriction on a width of the overlapping portion is relaxed, and the wide overlapping portion is realized. Therefore, an improvement in a withstand voltage between the second external terminal electrode formed on the end surface and an outermost turn of the first conductor pattern is realized. Similarly, regarding the second conductor pattern, the improvement in the withstand voltage between the first external terminal electrode formed on the end surface and an outermost turn of the second conductor pattern is realized. 本发明的平面线圈部件中，第1导体图形因为第4树脂壁的重叠部分从主体部的端面突出，相关于所以重叠部分宽度的制约被缓和并且实现了宽度宽阔的重叠部分。由此，就实现了被形成于端面的第2外部端子电极与第1导体图形的最外周匝之间的绝缘耐压的提高。同样，关于第2导体图形也是实现了被形成于端面的第1外部端子电极与第2导体图形的最外周匝之间的绝缘耐压的提高。
