To provide a thermal thermionic power generation element and a thermionic generation thermionic power generation module, capable of improving efficiency.SOLUTION: A thermionic power generation element includes a cathode 10, an anode 20, and an insulating member 40. The cathode includes an electrically-conductive material. The anode includes an electrically-conductive material. The insulating member is located between the cathode and the anode. The cathode and the anode have a gap 30 between the cathode and the anode. A first through-hole 22 is provided in the anode. The first through-hole extends through the anode in a first direction which is from the cathode toward the anode and communicates with the gap.SELECTED DRAWING: Figure 3 【課題】効率を向上できる熱電子発電素子及び熱電子発電モジュールを提供する。【解決手段】熱電子発電素子は、カソード１０と、アノード２０と、絶縁部材４０と、を備える。カソードは、導電材料を含む。アノードは、導電材料を含む。絶縁部材は、カソードとアノードとの間に設けられる。カソードとアノードとの間には、空隙部３０が設けられる。アノードには、第１貫通孔２２が設けられる。第１貫通孔は、カソードからアノードに向かう第１方向においてアノードを貫通し空隙部と連通する。【選択図】図３
