An energy conversion element comprising:
- an energy conversion film at least comprising a charged resin film consisting of a resin film at least containing a thermoplastic resin and a metal soap;
- and
- an electrode provided on at least one of two surfaces of the energy conversion film, wherein
- the metal soap is a salt of a fatty acid having 5 to 30 carbon atoms and aluminum;
- the resin film is a porous resin film having pores within the film;
- the porous resin film is a multilayer resin film comprising a core layer and a skin layer;
- the core layer comprises at least the thermoplastic resin, the metal soap, and a pore-forming nucleating agent;
- and
- the porous resin film has a porosity of 20% to 80%.
