The invention provides a wire-wound coil component to reduce a stray capacitance difference formed between a mounting substrate and each of first and second wires twisted together in a common mode choke coil in which the first and second wires are wound to improve mode conversion characteristics. In a stranded state of the first and second wires and as viewed from a mounting board side, the position where the first wire and the second wire are interchanged is shifted in the same circumferential direction of a winding core portion between adjacent turns. Thereby, it is possible to prevent a wire closer to a mounting substrate, that is, a wire that forms a larger stray capacitance from deviating to one of the first and second wires. 本发明提供一种绕组型线圈部件，其在卷绕有相互绞合的第一以及第二线的共模扼流圈中，为了得到良好的模式转换特性，缩小形成于安装基板与第一线以及第二线各自之间的寄生电容差。在从安装基板侧观察的第一线以及第二线的绞线状态下，第一线与第二线转换的位置在相邻的匝间在卷芯部的同一周向上错开。由此，能够防止更靠近安装基板的线即形成更大的寄生电容的线偏向第一线和第二线中的任一方。
