1. A heat generating method comprising:
heating, with a heater, a heat generating element and causing a first heat generating reaction in which the heat generating element generates heat with a first heat generation amount,
wherein the heat generating element including:
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,
wherein the multilayer film having a stacked configuration including; a first layer made of a hydrogen storage metal or a hydrogen storage alloy and having a thickness of less than 1,000 nm, and a second layer made of a hydrogen storage metal or a hydrogen storage alloy, which is different from that of the first layer, or ceramics and having a thickness of less than 1,000 nm;
triggering a second heat generating reaction in which the heat generating element generates heat with a second heat generation amount larger than the first heat generation amount, by imparting a perturbation to an input power to be applied to the heater in a state where the first heat generating reaction is occurring.
