Calcium alginate fibers were prepared by drying the fibroid gel made by ejecting the sodium alginate solution from a needle of a syringe to calcium chloride solution. The shapes of the fibers were observed, and physical properties such as the thickness and the tensile strength were evaluated. It was shown that according to the conditions of drying the fibroid gel, the shapes of the fibers were altered. For example, the structure like the joint of bamboo was formed by drying the gel put levelly on the waste paper. Concentration of the sodium alginate solution influenced the tensile strength of the fibers, but the thickness
