SMALL-SIZED POWER SUPPLY MODULE AND SEMICONDUCTOR MODULE

摘要

PROBLEM TO BE SOLVED: To provide a small-sized power generation device and a semiconductor module, capable of reducing thermal deterioration of a secondary battery chip mounted on a small-sized power supply module.SOLUTION: A secondary battery chip having a secondary battery main body part provided on a supporting substrate, and a thermoelectric power generation element are embedded by an embedded resin. A heat shield mechanism having a thermal conductivity lower than that of the embedded resin is provided between a surface contacted with the supporting substrate of the secondary battery main body part and the embedded resin.
