Abstract: Disclosed is a coil assembly and an electromagnetic cooking appliance. The coil assembly includes: a coil base, including a bottom wall and a side wall; a first coil and a second coil, fixedly located at the bottom wall and the side wall respectively; and a plurality of magnetic stripe supporters, located at the coil base along a circumferential direction. Each magnetic stripe supporter includes a first mounting part, a second mounting part, and a connecting part connected to the first mounting part and the second mounting part. The coil assembly in the disclosure can effectively reduce the mounting space for the magnetic stripe supporter, and prevent the interference between the magnetic stripe supporter and the circuit board supporter in the electromagnetic cooking appliance.
