1. A method of producing a guest-free silicon clathrate, comprising:
a synthesizing step of performing a heat treatment on a mixture containing Si as a material serving as a host and a material serving as a guest to synthesize a silicon clathrate compound;
a stirring step of stirring the silicon clathrate compound contained in a container, performed by using a protrusion on an inner wall surface of the container;
a guest removing step of irradiating the silicon clathrate compound contained in the container with an electromagnetic wave from an outside of the container to remove the guest while suctioning gas inside the container and while rotating the container, wherein the container is made of transparent quartz glass; and
an adsorbing step of adsorbing the removed guest using a cooling member and an adsorbent.
