Disclosed are an electronic apparatus and a connecting device. The electronic apparatus includes a body; a supporting frame located at a back face of the body; a connecting device through which the supporting frame is rotatably connected with the body so that the supporting frame is unfolded by a predefined angle relative to the back face of the body and that the body is supported on the support surface through the supporting frame; the connecting device including: a first connecting part connected with the supporting frame; a second connecting part connected with the body; a rotary shaft; a first damping element; a second damping element; wherein in the case that the supporting frame is rotated, relative to the back face of the body, by the predefined angle around the rotary shaft in a first direction through the connecting device, the first damping element of the connecting device provides a first damping force against rotation in the first direction; in the case that the supporting frame is rotated, relative to the back face of the body, by the predefined angle around the rotary shaft in a second direction through the connecting device, the second damping element of the connecting device provides a second damping force against rotation in the second direction, the first direction is opposite to the second direction, and the first damping force is different from the second damping force.
