PROBLEM TO BE SOLVED: To provide a Coriolis flowmeter which eliminates stresses by a temperature variation acting on a straight flow tube, while maintaining a shape of the flow tube. SOLUTION: The Coriolis flowmeter comprises the flow tube 3, consisting of a partially formed tube 3b and the partially constituted tube 3a of two pieces, and the partially constituting tubes 3b, 3a which have the same diameter. The partial formed tube 3b has a length which is longer than a section installing a drive section and a pair of sensors (not shown); an expanded aperture 4b of the partially constituted tube 3b and the expanded aperture 4a of the partial formed tube 3a are connected by an outer circumference welded section 5 facing coaxially; and an expanded section is constituted at both ends of the partial formed tube 3b.
