Fiber plate, manufacturing method thereof, radiation imaging apparatus and radiation imaging system

A fiber plate comprising:

• a plurality of fibers;
• multi-fibers formed by bundling and drawing the plurality of fibers to take one polygonal shape in section so that the multi-fibers can be air-tightly stacked without any air gap;
• and
• a multi-fiber aggregate formed by bundling and drawing the multi-fibers to take other polygonal shape in section that enables air-tight stacking with no air gap so as to be analogous to or different from the one polygonal shape in section,
• wherein the fiber plate is configured by air-tightly bonding the multi-fiber aggregates to each other with a bonding agent without the air gap in a state of keeping the one or other polygonal shape in section after being drawn.

A fiber plate manufacturing method comprising:

• a step of manufacturing a multi-fiber by bundling and drawing a plurality of fibers to take one polygonal shape in section so that the multi-fibers can be air-tightly stacked without any air gap;
• a step of manufacturing a multi-fiber aggregate by bundling and drawing the multi-fibers to take other polygonal shape in section that enables air-tight stacking with no air gap so as to be analogous to or different from the one polygonal shape in section;
• and
• a step of manufacturing a fiber plate by air-tightly bonding the multi-fiber aggregates to each other with a bonding agent without the air gap in a state of keeping the one or other polygonal shape in section after being drawn.
