Abstract
A heat generating device includes a container, a heat generating element, and a heater. A hydrogen-based gas contributing to heat generation is introduced into the container. The heat generating element is provided inside the container. The heater is configured to heat the heat generating element. The heat generating element includes a base made of a hydrogen storage metal, a hydrogen storage alloy, or a proton conductor, and a multilayer film provided on a surface of the base. The multilayer film having a stacking configuration of: a first layer that is made of a hydrogen storage metal or a hydrogen storage alloy, and a second layer that is made of a hydrogen storage metal, a hydrogen storage alloy, or ceramics different from that of the first layer. The first layer and the second layer have a layer shape with a thickness of less than 1000 nm.
