The tube set, which is provided in a tube pump that feeds a liquid, includes a pump tube and a holder. The holder has a flexible flat plate and includes first engagement portion and second engagement portions that arc located away from each other in a first direction. The first engagement portion and second engagement portions are configured to be fitted into first engagement groove and second engagement grooves formed in the housing, respectively, when the holder is pushed into the housing in a state of being bent in a thickness direction. The holder is elastically restored to be attached to the housing when the first engagement portion and the second engagement portions are fitted into the respective first engagement groove and the second engagement grooves, respectively. The holder has a flexural modulus of 500 MPa or more and 3500 MPa or less.
