A conductive path structure includes a conductor that includes a first conductive portion and a second conductive portion which are connected to each other through a cut-off facilitating portion, and a semi-solid state insulation member that is in a semi-solid state and covers the cut-off facilitating portion. When the cut-off facilitating portion is cut off so as to separate the first conductive portion and the second conductive portion to each other due to an impact applied to the cut-off facilitating portion, the semi-solid state insulation member covers end portions of the separated first conductive portion and the separated second conductive portion which are close to the cut-out facilitating portion.
