PURPOSE:To prevent a gain of a microchannel plate from being lowered after vacuum baking thereof as well as improve a life thereof by employing acid- soluble glass of a specific composition. CONSTITUTION:Glass element wires yielded by converting an acid-soluble glass core material with acid resistant glass are tied up in a parallel bundle and heated to be welded with each other, and furthermore cut in a direction of crossing to the element wires to be formed into a plate shape. In a method of manufacturing a microchannel plate wherein the acid-soluble glass core material is dissolved with acid to permit electrodes to be formed on both surfaces thereof, while an internal surface of a channel is activated, magnesium oxide of alkali earth metal or a component including magnesium oxide and calcium oxide is incorporated into the acid resistant glass, whereby a microchannel plate can be assured, which shows a higher gain and stable operation characteristics.
