Abstract
Abstract An optical fiber-connecting reinforcing member including a resin sheet having excellent heat resistance and peelability, and at least one laminate arranged on a surface of the resin sheet. The laminate consists of a reinforcing base plate made of a ceramic and a hot melt film. The hot melt film is bonded to the resin sheet. A process for producing optical fiber-connecting reinforcing member is also disclosed. A resin sheet having excellent heat resistance and peelability is first placed on a lower holding plate with a guide, and setting a perforated plate onto the upper surface of the resin sheet. The perforated plate has longitudinal through holes bored therethrough at a specific interval. Hot melt films and reinforcing base plates are each preliminarily cut to a given size, and inserted into the longitudinal holes. An upper holding plate is placed on the perforated plate, and then hot pressing is effected.
