(54) | METHOD FOR MANUFACTURING THERMOELECTRIC CONVERTER |
(57) An insulating substrate (10) is prepared. In the substrate, plurality via holes (11
and 12) penetrating in a thickness direction are filled with a conductive paste (41
and 51). This paste is produced by adding an organic solvent to a powder of an alloy
in which a plurality of metal atoms retain a predetermined crystalline structure,
and by processing the powder to a paste. The insulating substrate (10) is then pressed
from a front surface (10a) and a back surface (10b) of the insulating substrate (10),
while being heated. The conductive paste (41 and 51) is solid-phase sintered and interlayer
connecting members (40 and 50) are formed. A front surface protective member (20)
is disposed on a front surface (10a) of the substrate (10) and a back surface protective
member (20) is disposed on a back surface (10b) of the substrate (10), and a laminate
(80) is formed. The laminate (80) is integrated by a lower pressure being applied
while heating at a lower temperature, compared to the temperature and pressure in
the process of forming the interlayer connecting members (40 and 50).
