To provide a power generator capable of effectively recovering waste heat from an engine body part.SOLUTION: Provided is a power generator 10 which generates power by recovering waste heat from an engine 20. The power generator 10 comprises a Peltier element part 11 including: a low-temperature side metal plate part 15 cooled by a coolant; and a high-temperature side metal plate part 13, disposed on an engine body part 20A side with respect to the low-temperature side metal plate part 15, and fitted so as to be capable of transmitting the waste heat from the engine 20 to the engine body part 20A. The Peltier element part 11 can generate power by the temperature difference between the low-temperature side metal plate part 15 and the high-temperature side metal plate part 13. The Peltier element part 11 serves as an engine cover covering at least an upper portion of the engine body part 20A.SELECTED DRAWING: Figure 2 【課題】、エンジン本体部からの廃熱を効果的に回収可能な発電装置を提供する。【解決手段】エンジン２０の廃熱を回収して発電する発電装置１０であって、冷媒により冷却される低温側金属板部１５と、低温側金属板部１５よりもエンジン本体部２０Ａ側に配されており、エンジン本体部２０Ａに対してエンジン２０からの廃熱を伝達可能に取り付けられた高温側金属板部１３と、を含み、低温側金属板部１５と高温側金属板部１３とに生じる温度差により発電可能なペルティエ素子部１１を備え、ペルティエ素子部１１がエンジン本体部２０Ａの少なくとも上部を覆うエンジンカバーをなすようにした。【選択図】図２
