PROBLEM TO BE SOLVED: To provide a dynamics characteristic evaluation system of microneedle which can apply uniform biaxial tensile stress with a sufficient reproducibility to a thin film, moreover, can also easily deal with the thin film with minuteness and hydrous property. SOLUTION: A dynamics characterization system of a microneedle 50 includes: a holder unit 51 which provides a placing plate 25 in which a punch transit hole 30 is processed in formation by penetration, and a thin film U is placed on its top surface, and a thin film pressing plate 26 in which a needle transit hole 28 is processed in the formation by penetration, and the thin film U is processed in press fixation on the thin film placing plate 25; a punch unit 52 in which at least a tip of the thin film side is formed cylindrically, and the thin film U is pressed from the rear surface side; and a needle unit 53 which pierces a microneedle 47 with respect to a part pressed by a punch unit 3 among the thin film U from its front side.
