PROBLEM TO BE SOLVED: To provide a Coriolis mass flowmeter which uses two parallel flow tubes corresponding to temperature variation, and which has simple and compact characteristics of a straight tube type that are fundamentally existed in a straight tube type Coriolis mass flowmeter. SOLUTION: Inlet side and outlet side manifolds 24, 25 are continuously curved to each connection end of each of two flow tubes 1, 2. Two flow tubes 1, 2 are composed of zenithal part consisting of a straight tube, and both side leg parts which are connected to each the connection end of the inlet side and the outlet side manifolds 24, 25 continuously curved in the one direction from both ends of the zenithal part. Both side leg parts are set to a minimum length which is required to curve the flow tubes 1, 2. A driving device 15 and a pair of vibration detecting sensor 16, 17 are respectively mounted on the zenithal part consisting of the straight tube.
