PROBLEM TO BE SOLVED: To provide a weighing apparatus for thinning a component force buffer, and then reducing a height. SOLUTION: In the weighing apparatus, the component force buffer 70 for releasing a horizontal component force is disposed between a support member 50 for supporting a load including an object to be weighed and a load detecting section 40. The component force buffer 70 includes an array of a plurality of needle bearings disposed in parallel, and enables a linear movement in the direction of the array of the needle bearings relative to the support member 50 and the load detecting section 40 between which the component force buffer 70 is disposed. The component force buffer in which a plurality of the needle bearings are disposed in parallel has a thickness as much as 1/4 of a thickness of the component force buffer using a ball, and is used for the weighing apparatus. The weighing apparatus is thinned so as to reduce the height of the weighing apparatus. A rigidity reference of the support member and a cost of the apparatus can be reduced by configuring the linear movement direction of the component force buffer so as to compensate the rigidity of the support member.
