Zusammenfassung:	PROBLEM TO BE SOLVED: To precisely provide a composite material structure enhanced in strength and rigidity with high productivity.SOLUTION: The continuous fiber composite material structure is composed of continuous fiber bundles arranged in a state substantially parallel to each other and thermoplastic resin and has a twist. The structure includes a part having a twist ratio of 1/(20×d) (where d is the width of the structure in a direction crossing the orientation direction of continuous fibers at a right angle before the twist is imparted) or higher (A), and (B) and (A) and satisfying that the sum total of the twist angles of the part having the twist ratio of 1/(20×d) or higher is 60° or higher (B) with respect to a skeletal line connecting centers in the width direction of the structure in a direction crossing the orientation direction of the continuous fiber bundles at a right angle without buckling the continuous fiber bundles.
