摘要： An electrode containing a clathrate compound is disclosed that is more likely to withstand load involved in repetition of penetration and desorption of, e.g., lithium ions compared to no guest substance-encapsulating silicon clathrate compounds. An electrode active material making up the electrode according to the present invention includes a clathrate compound. The clathrate compound contains a crystal lattice and a guest substance. The guest substance is encapsulated in the crystal lattice. It is preferable that the clathrate compound be a main component of the electrode active material that makes up the electrode.
