Abstract
Provided are a p-type thermoelectric conversion material, a thermoelectric conversion module, and a method of manufacturing a p-type thermoelectric conversion material that are capable of obtaining high thermoelectric conversion characteristics. The p-type thermoelectric conversion material has a full Heusler alloy having a composition represented by the following General Formula (1) and has a relative density of 85% or more, FeTiMAMB. . . (1), wherein in Formula (1), MA is one element selected from the group consisting of Si, Sn, and Ge, MB is one element selected from the group consisting of Al, Ga, and In, and x, y, a, and b are numbers set so that x+y+a+b=100, a+b=z, 50<x≤52.5, 20≤y≤24.5, 24.5≤z≤29, a>0, and b>0 in atom %, respectively.
