Abstract
Provided is a composite member including: an inorganic matrix part made from an inorganic substance that includes at least one of a metal oxide or a metal oxide hydroxide as a main component, contains substantially no single metal and alloy, and is a diamagnetic substance or a paramagnetic substance; and a ferromagnetic material part that is present inside the inorganic matrix part, directly bonds with the inorganic substance making up the inorganic matrix part, and is made from a ferromagnetic substance. In the inorganic matrix part, particles of the inorganic substance are continuously present, and the inorganic matrix part has a larger volume ratio than that of the ferromagnetic material part.

A composite member comprising:
- an inorganic matrix part including multiple particles made from an inorganic substance that includes at least one of a metal oxide or a metal oxide hydroxide as a main component, contains substantially no single metal and alloy, and is a diamagnetic substance or a paramagnetic substance, the particles made from the inorganic substance bonding with each other to form the inorganic matrix part;
- and
- a ferromagnetic material part that is present inside the inorganic matrix part, directly bonds with the inorganic substance making up the inorganic matrix part, and is made from a ferromagnetic substance, and
- a connection part derived from the inorganic substance and formed between the inorganic substance and the ferromagnetic material part, within the inorganic substance, and within the ferromagnetic material part, the connection part being an amorphous part,
- wherein in the inorganic matrix part, the particles of the inorganic substance are continuously present, and
- wherein the inorganic matrix part has a larger volume ratio than that of the ferromagnetic material part, and
- wherein the inorganic matrix part is a polycrystalline substance.
