The present invention has a network structure of a polymer chain selected from polysilane, polygerman and polystanan, and copolymers thereof, and a metal oxide in which a metal atom is bonded to another metal atom through an oxygen atom. A glass matrix composed of a network structure of the metal oxide, which is chemically crosslinked, and has a volume resistivity of 3 × 10 6 Pa · cm or less measured by a circular plate electrode method with a voltage / film thickness ratio of 10 6 V / cm. It is about the material. |
