Abstract

P-type semiconductor sheets and n-type semiconductor sheets formed by mixing a powder of semiconductor material, a binder resin, a plasticizer, and a surfactant are prepared. In addition, separator sheets formed by mixing a resin such as PMMA and a plasticizer are prepared. Through holes are formed in each of the separator sheets and then filled with a conductive material. Thereafter, the p-type semiconductor sheet, the separator sheet, the n-type semiconductor sheet and the separator sheet are stacked. The resultant laminated body is cut into a predetermined size and then subjected to a baking process.

First claim

The invention claimed is:

1. A thermoelectric conversion element comprising:
p-type semiconductor blocks and n-type semiconductor blocks alternately arranged in a first direction;
a plurality of electrodes connecting the p-type semiconductor blocks and the n-type semiconductor blocks to each other; and
a pair of heat transfer plates arranged to hold the p-type semiconductor blocks and the n- type semiconductor blocks therebetween in a second direction orthogonal to the first d…
