Abstract

A ribbon laminated body used for creating a honeycomb core is constituted by a plurality of layers of ribbons laminated, a low-temperature curing adhesion portion, and a high-temperature curing adhesion portion. A low-temperature curing adhesion portion adhesively bonds adjacent ribbons, and a high-temperature curing adhesion portion is in contact with both ribbons. At a portion where the low-temperature curing adhesion portion is in contact with a ribbon, the shape of the low-temperature curing adhesion portion is a trapezoidal shape, wherein an upper base is overlapped with a part of one long side of the ribbon, and a lower base is overlapped with a part of the other long side of the ribbon. At a portion where the high-temperature curing adhesion portion is in contact with the ribbon, a part of a periphery of the high-temperature curing adhesion portion is in contact with an oblique side a low-temperature curing adhesion portion.
