Zusammenfassung:	Provided is a heat/acoustic wave conversion unit which improves durability and energy conversion efficiency. A heat/acoustic wave conversion unit 100 includes: a heat/acoustic wave conversion component 1 including a partition wall 11 that defines a plurality of cells 14; and two heat exchangers 2, 3 that exchange heat with both end parts of the heat/acoustic wave conversion component 1. Hydraulic diameter HD of the cells 14 in the heat/acoustic wave conversion component is 0.4 mm or less, and a ratio HD/L of the hydraulic diameter HD to the length L of the heat/acoustic wave conversion component is 0.005 or more and less than 0.02. One of the heat exchangers includes: a heat-exchanging honeycomb structure 20, and an annular tube 21 that surrounds a circumferential face of the heat-exchanging honeycomb structure and defines a channel through which the heated fluid flows. The annular tube includes a structure body that is disposed in the channel to increase a contact area with the heated fluid, an inflow port into which the heated fluid flows, and an outflow port through which the heated fluid flows out. At least one of the heat-exchanging honeycomb structure and the structure body is made of a ceramic material that contains SiC as a main component.
