A cooking apparatus includes a communicator that communicates with a terminal, a link-state manager that manages link-state information indicating whether or not a link to the terminal is active, a heater that performs a heating operation on a cooking tool, a receiver that receives a user operation, and a controller that controls the communicator or the heater which is a control target, on the basis of the user operation. In the case where the link is active, when the user operation is performed on the receiver, the controller causes the communicator to transmit instruction information to the terminal. The instruction information indicates an instruction to switch an image being displayed on the information display apparatus from a first image to a second image.
