A weighing device (1) has a load-bearing portion (10) that supports an object being weighed, a plurality of transition portions (20), and a separation portion (30). The transition portions are positioned on the separation portion, and the load-bearing portion is positioned on the transition portions, with the transition portions connected to the load-bearing portion and the separation portion. A plurality of weighing sensors (40) are provided at a bottom of the separation portion. A support portion (50) is below the weighing sensors to provide support therefor. The weighing device simplifies the loading condition of weighing sensors and isolates the horizontal mechanical deformation/distortion of the weighing load-bearing mechanism. It also reduces the influence of mechanical deformation/distortion, thereby improving the weighing performance and the effectiveness of the weighing device.
