1. A gap-filling method, comprising:
filling a gap of a structure having the gap therein by inserting a threadlike adhesive body into and along the gap,
wherein
in a cross-sectional view, the structure has a first side and a second side different from the first side,
in the cross-sectional view, the gap is a space between a first surface of the structure and a second surface of the structure opposite to the first surface,
in the cross-sectional view, the gap has an opening by which the space is exposed to an environment on the first side of the structure,
in the cross-sectional view, the opening of the gap has a width between a first point and a second point, the first point is located at a first position wherein the first surface of the structure intersects the first side of the structure, and the second point is located at a second position wherein the second surface of the structure intersects the first side of the structure,
the threadlike adhesive body, before being inserted into the gap, has a diameter which is 1.0 to 4.0 times the width of the opening of the gap, and
the threadlike adhesive body is inserted into the gap so as to come into contact with at least the first surface of the structure, the second surface of the structure, the first point and the second point.
