PROBLEM TO BE SOLVED: To provide a warmer which warms a thermal storage substance uniformly by irradiating the whole area of a bag uniformly with microwaves without allowing microwaves to be concentrated at corner parts of a storage part of the bag with the thermal storage substance sealed therein. SOLUTION: The warmer 1 is provided with the thermal storage substance 2 and the bag 3 having the thermal storage substance 2 sealed water-tight in the storage part 8, and constituted so as to be warmed by a microwave oven. Regarding the warmer 1, the shape of the corner parts 7 of the storage part 8 of the bag 3 is arc-shaped, and the shape the edge part 5 of the storage part 8 is arc-shaped. It is more desirable that the thermal storage substance 2 sealed water-tight in the storage part 8 of the bag 3 is a gel substance containing water absorbing resin and water.
