Cooking apparatus

A cooking apparatus comprising:

• a cooking chamber in which food is cooked and being open in a first direction and comprising support parts formed on opposite sides of the cooking chamber;
• a shelf configured to be inserted into the cooking chamber in the first direction and on which food is placed;
• and
• a magnetron configured to generate a high frequency to be supplied to the shelf,
• wherein the shelf comprises:
• a holder having a long side extending in a second direction orthogonal to the first direction and a short side extending in the first direction;
• a first container and a second container configured to be seated on the holder and in which food is placed, respectively, the first container having a first cooking surface on which food is placed in the first container in a third direction orthogonal to the first and second directions, and the second container having a second cooking surface on which food is placed in the second container in the third direction;
• and
• a first heat generating member on an opposite side of the first cooking surface on which food is placed and a second heat generating member on an opposite side of the second cooking surface on which food is placed configured to generate heat by the high frequency generated from the magnetron to transfer the heat to the first and second containers, respectively, wherein the first heat generating member is formed of a first material composition to provide heat of a first temperature when absorbing the high frequency, and the second heat generating member is formed of a second material composition to provide heat of a second temperature when absorbing the high frequency, and
• wherein the first heat generating member comprises a ferrite material, the second heat generating member comprises a ferrite material, and a content of the ferrite material in the first heat generating member and a content of the ferrite material in the second heat generating member are different, and
• wherein the holder is mountable on the support parts and the first container and the second container are configured to be disposed side by side in the second direction and to be detachably seated in a third direction orthogonal to the first and second directions with respect to the holder.
