1. A long object guiding device comprising a long flexible tubular member and being configured to guide a flexible long object inserted through the tubular member while protecting, with the tubular member, the long object in correspondence with displacement of the tubular member, wherein
the tubular member has a long sheet shape in an unfolded state,
a longitudinal direction of the tubular member intersects a width direction of the tubular member,
a first joint portion is disposed on one side edge of the tubular member in the width direction to extend in the longitudinal direction,
a second joint portion is disposed on an other side edge of the tubular member in the width direction to extend in the longitudinal direction, the second joint portion being configured to be joined to and disjoined from the first joint portion,
at least one end of the tubular member in the longitudinal direction has a passage portion that allows for passage of an end of the long object, and
the passage portion is a notch formed by cutting out a certain region from an end edge of the tubular member in the longitudinal direction or a slit formed by cutting a portion having a certain length from the end edge.
