PROBLEM TO BE SOLVED: To improve insulation performance of a circuit board connected to a connector housing.SOLUTION: A circuit board comprises: a plurality of conductive parts 3 which are arranged on a base material 2 in a width direction W of a circuit board 1; and an insulating covering part 4 which partially covers the plurality of conductive parts 3. Each of the plurality of conductive parts 3 has a first part 31, a second part 32 and a third part 33. The first part 31 is provided at a position to be housed in a connector housing 6. The second part 32 is covered with the covering part 4. The third part 33 is located between the first part 31 and the second part 32 and not covered with the covering part 4. A wide dimension of the third part 33 along the width direction W is smaller than a width dimension of the first part 31 in the width direction W.SELECTED DRAWING: Figure 3 【課題】コネクタハウジングに接続される回路基板の絶縁性能を向上させる。【解決手段】複数の導電部３は、基材２上において回路基板１の幅方向Ｗに配列されている。絶縁性の被覆部４は、複数の導電部３の一部を覆っている。複数の導電部３の各々は、第一部分３１、第二部分３２、および第三部分３３を有している。第一部分３１は、コネクタハウジング６に収容される位置に設けられている。第二部分３２は、被覆部４に覆われている。第三部分３３は、第一部分３１と第二部分３２の間に位置しており、被覆部４に覆われていない。第三部分３３の幅方向Ｗに沿う幅寸法は、同方向に沿う第一部分３１の幅寸法よりも小さい。【選択図】図３
