Claim:
1. A protector made of a shape-memory polymer sheet with a glass transition point temperature Tg set to a temperature higher than 50° C., and constituted by a tube-forming flat surface portion and a tape fixing portion extending from the tube-forming flat surface portion, the tube-forming flat surface portion being formed with a predetermined rectangular shape having a width and a plurality of lengthwise edges for being folded into a rectangular tube shape that allows a group of electrical lines to be inserted and concealed therein, and being shaped as a flat plate with the tape fixing portion extending from at least one end in a lengthwise direction, the protector being caused to form the rectangular tube shape with the plurality of lengthwise edges and to remember the rectangular tube shape with the plurality of lengthwise edges at a predetermined temperature that is higher than the glass transition point temperature Tg, and then caused to return to the flat plate shape at a temperature in a vicinity of the glass transition point temperature Tg, and then fixed in the flat plate shape in a temperature range lower than the glass transition point temperature Tg.
