description PROBLEM TO BE SOLVED: To provide a coriolis flowmeter having high measurement accuracy.SOLUTION: A coriolis flowmeter 1 whose flow tube 2 is linear comprises the linear flow tube 2 and a linear vibrating body 3 in parallel with it. The vibrating body 3 is constituted by joining piezoelectric elements 4a, 4b to an elastic body 6 that is made of stainless steel and has a rectangular cross section. The flow tube 2 made of stainless steel has a rectangular cross section and a circular flow channel in its center. The flow tube 2 is bonded with piezoelectric elements 4c, 4d, 4e, 4f for detecting distortion caused by Coriolis force. The piezoelectric elements 4c, 4d, 4e, 4f are bonded to positions where distortion by Coriolis force becomes maximum in the flow tube 2. Also, the vibrating body 3 is constituted by bonding the piezoelectric elements 4a, 4b to positions where vibration displacement of the stainless-steel elastic body 6 can be maximum. The flow tube 2 and the vibrating body 3 have both ends that are welded to stainless-steel support parts 5a, 5b. Further, the support parts 5a, 5b are welded to a base part 7 made of stainless steel.
