A collagen material is characterized in being constituted of a collagen gel fragment wherein a shape of the collagen gel fragment is a string and the string collagen gel fragments couple with each other by drying, and the collagen gel fragments have orientation obtained by giving a flow of a fixed direction to collagen solution during a process of gelating a collagen solution. A method of producing a collagen material comprises a step for preparing a string collagen gel formed and orientated by collagen solution being extruded through a nozzle into a container containing a phosphate buffered saline, and giving a flow of a fixed direction to the collagen solution wherein a shape of the collagen gel is a string and the direction of the orientation of the string collagen gel is a direction of the string shape, a step for obtaining multiple string collagen gels wherein the orientation are controlled, a step for arranging the multiple collagen gels in a desired shape, and a step for drying the multiple collagen gels arranged in the desired shape to couple with the collagen gels each other.
