To provide a heat exchanger which is inexpensive and small and can stabilize a temperature of a first heat medium discharged therefrom.SOLUTION: Heat exchange tubes (11 to 15) include at least one specific heat exchange tube (13). An interior of the specific heat exchange tube (13) is partitioned into a passage F1 (F1) having fins 90 and a passage (F2) which conducts heat exchange dealing with a smaller heat quantity than that of the passage F1 (F1) due to no fins 90 being provided therein.SELECTED DRAWING: Figure 3 【課題】安価且つ小型でありながら、排出される第１の熱媒体の温度を安定させることができる熱交換器を提供すること。【解決手段】複数の熱交換チューブ（１１〜１５）は、少なくとも１つの特定熱交換チューブ（１３）を含んでいる。この特定熱交換チューブ（１３）の内部は、フィン９０を有している流路Ｆ１（Ｆ１）と、フィン９０を有していないことにより流路Ｆ１（Ｆ１）よりも少ない熱量の熱交換を行う流路（Ｆ２）と、に区画されている。【選択図】図３
