1. A cooking appliance comprising:
a housing that defines a cavity therein;
a door connected to the housing and configured to open and close the cavity;
a microwave (MW) heating module configured to emit microwaves into the cavity; and
an induction heating (IH) module configured to emit a magnetic field toward the cavity,
wherein the IH module comprises a shielding member through which the magnetic field generated by a working coil of the IH module passes, the shielding member being configured to block the microwaves emitted from the MW heating module,
wherein the shielding member comprises any one of carbon paper or carbon fabric woven with carbon fiber,
wherein the IH module further comprises a plate and a plurality of connection members, the plurality of connection members being positioned on vertically opposite sides of both the plate and the shielding member, and
wherein the plurality of connection members comprise:
a first connection member that passes through the plate and that protrudes into the cavity, the first connection member partitioning the plate into a heating region and a non-heating region, and
a second connection member that is positioned between the shielding member and the working coil and that fixes the shielding member to the plate together with the first connection member.
