To provide a dish-warming case which does not suffer breakage of a lead wire for supplying power to a heater and enables effective usage of a shelf area.

A heat plate 4 containing the heater 10 is fixed in a box body 3 roughly horizontally. A shelf 5 is tightly and slidably attached on the heat plate 4. Even if the shelf 5 is moved to put in or take out dishes, the heater 10 and the heat plate 4 keep their position against the box body 3 and the lead wire 15 which supplies power to the heater 10 does not change its bending state and posture. Therefore, wire breakage caused by repetition of bending and stretching does not happen on the lead wire 15. In addition, because of no change in the bending state and posture, dishes never make a contact with the lead wire 15 when the shelf 5 is moved. This enables the user to put dishes by effectively using the whole area of the shelf 5.
