An electric assist cart includes: a body frame where a burden can be loaded; a drive wheel provided in the body frame; a control handle by which an operator can input a driving force to the body frame; a torque sensor that detects a driving torque applied to the body frame by pushing and handling the control handle; an electric motor that applies an assisting force to the drive wheel depending on the driving torque detected by the torque sensor; and a controller that computes the assisting force applied to the drive wheel and supplies an electric current to the electric motor depending on the assisting force, wherein the controller has a plurality of modes having different characteristics for a change of a magnitude of the electric current depending on the driving torque, and the electric current can be supplied to the electric motor by switching the mode.
