A heat exchanger for a combustion apparatus capable of providing satisfactory sealing between an open end of an oxidizing agent duct and a regenerative structure. A regenerator (8) includes a high-temperature section constituted by a regenerative unit (10) made of a ceramic material and a low-temperature section constituted by a regenerative unit (9) made of a metal material. The regenerator is formed with a plurality of communication passages which permit a combustion chamber and a suction/exhaust duct structure (22) to communicate with each other. The communication passages are provided by a plurality of through-holes formed in the regenerative units. The number of the through-holes and an equivalent diameter thereof are determined so as to permit a pressure loss gradient in the low-temperature section positioned on the side of the suction/exhaust duct structure to be larger than that in the high-temperature section positioned on the side of the combustion chamber. <IMAGE>
