Abstract

A heating apparatus such as a microwave oven includes a generally rectangular box-shaped cooking chamber (4) in which food (11) to be cooked is accommodated, a magnetron (12) supplying microwaves into the cooking chamber (4) so that the food (11) is heated, and a temperature sensor (14) including a plurality of infrared sensing elements (19) and disposed on an upper portion of the cooking chamber (4) so as to be away from two center lines (A1, A2) passing centers of two pairs of opposite sides (4a, 4b; 4c, 4d) of the cooking chamber (4) as viewed from above, whereupon the temperature sensor (14) detects temperatures at a plurality of locations (23a) in the cooking chamber (4) respectively.
