PROBLEM TO BE SOLVED: To provide a pulsation absorber of a flowmeter capable of efficiently absorbing pressure variations and pulsations without forming a large-sized meter or increasing costs. SOLUTION: The pulsation absorber of the flowmeter includes both a movable wall 4 and a bellows 6. The movable wall 4 communicates with a flow measuring part through an opening part 3 provided for a channel wall 2, forms part of a channel A, and is mounted in such a form as to be located outside the channel wall 2 on the fixed side. The bellows 6 forms a part 5 for absorbing pressure variations in a channel pipe by the approximately parallel movement of the movable wall 4 while maintaining an interval to the fixed-side channel wall 2 and volumetic changes according to the pressure in the channel pipe.
