PROBLEM TO BE SOLVED: To provide a micropiping and its manufacturing method which are superior in impact resistance, working accuracy, mass production and manufacturing cost. SOLUTION: The micropiping 10 comprises a base plate 21 on which a micro flow path is formed by grooving work, a cover base plate 19 connected to the base plate 21 so that it may cover the flow path, and the like. When a polymer material is molded by such as a transfer molding and an injection molding using an original form 20 having a three-dimensional shape of the flow path, the base plate 21 with the flow path transferred is obtained. When the cover base plate 19 comprising a thermoplastic resin sheet or the like is connected onto the molded base plate 21, the micropiping 10 is obtained.
