PROBLEM TO BE SOLVED: To provide a manufacturing method for easily and inexpensively manufacturing a medical tube.SOLUTION: A method for manufacturing a medical tube MTB in which a first tube TB1 and a second tube TB2 are connected to each other includes: an inserting step of inserting the second tube TB2 into an inner cavity LN1 of the first tube TB1; and a welding step of welding both tubes TB1, TB2 to each other by applying frictional heat to a part where both tubes TB1, TB2 are overlapped with each other under displacement restrictions for restricting the displacement of the surfaces of both tubes TB1, TB2, which are the first tube TB1 and the second tube TB2. |
