A method of manufacturing microchannel plate according to an embodiment of the present invention includes: a first step of fabricating a multifiber having a polygonal cross-section by bundling a plurality of fibers; a second step of fabricating a microchannel plate base material by use of a plurality of the multifibers; and a third step of fabricating a microchannel plate out of the microchannel plate base material. The plurality of fibers include: a first fiber whose predetermined-thickness outer circumferential part surrounding a center part including a core is formed of a predetermined-component glass material; and a second fiber whose both center part including a core and outer circumferential part surrounding the same are formed of the predetermined-component glass material. The second fiber is arranged at, at least, one corner of a polygonal cross-section of the multifiber.
