Scintillator panel, radiation image sensor, and method of making scintillator panel

A scintillator panel comprising:

• an optical component in which a plurality of optical members, each having entrance and exit end faces substantially parallel to each other and being composed of a plurality of optical fibers arranged, are arranged such that said entrance end faces are disposed on substantially the same plane and said optical members adjacent each other are bonded with an adhesive;
• and
• a scintillator deposited on said entrance end faces arranged;
• wherein at least one of said optical members adjacent each other has an optical fiber axis forming an acute angle with said entrance end face;
• wherein each of said optical members adjacent each other is arranged such that said optical fibers respectively constituting each of said optical members have a gap therebetween widening from said entrance end face side to said exit end face side;
• and
• wherein each side face of said optical members adjacent each other on said entrance end face side is formed with a ground surface in which said optical members are ground against each other.

• an arrangement step of arranging each of said optical members adjacent each other such that said optical fibers respectively constituting each of said optical members have a gap therebetween widening from said entrance end face side to said exit end face side;
• a forming step of forming contact surfaces on each of respective side faces of said optical members adjacent each other on said entrance end face side;
• a bonding step of bonding with an adhesive said optical members adjacent each other;
• and
• a depositing step of depositing a scintillator on said entrance end faces arranged.
