PROBLEM TO BE SOLVED: To provide a folding sheet capable of easily extending it by one operation and folding it. SOLUTION: A sheet of the folding sheet is composed of having at least two sheets of trunk parts consisting of a left side trunk part and a right side trunk part, and at least two sheets of leaf parts, connecting the left side trunk part and the right side trunk part through a folding line (13), connecting the trunk parts and the leaf parts through folding lines (14), and connecting two sheets of adjoining leaf parts through a folding line (15) so as to form a pair. In addition, the folding line (14) connected with the folding line (13) of a ridge-folding line is a ridge-folding line, and the folding line (14) connected with the folding line (13) of a valley-folding line is a valley-folding line, and the folding line (15) is the valley-folding line when it is on an extending line of the ridge-folding line (13), and is the ridge-folding line when it is on an extending line of the valley-folding line (13), and in addition, under a folded condition, the leaf parts (12) are pinched between the trunk parts (11).
