Abstract
A method for producing a heat transfer suppression sheet contains processing a mixture into a sheet by a dry method, the mixture containing an inorganic particle and a binder fiber having a core-sheath structure. The binder fiber having a core-sheath structure includes a core portion extending in its longitudinal direction, and a sheath portion formed to cover an outer peripheral surface of the core portion, and a melting point of a first organic material constituting the core portion is higher than a melting point of a second organic material constituting the sheath portion.

A method for producing a heat transfer suppression sheet comprising:
- processing a mixture into a sheet by a dry method, the mixture containing an inorganic particle and a binder fiber having a core-sheath structure, wherein
- the binder fiber having a core-sheath structure includes a core portion extending in a longitudinal direction of the binder fiber, and a sheath portion formed to cover an outer peripheral surface of the core portion, and
- a melting point of a first organic material constituting the core portion is higher than a melting point of a second organic material constituting the sheath portion.
A heat transfer suppression sheet comprising:
- an inorganic particle;
- an organic fiber constituted of a first organic material;
- and
- a fusion portion covering an outer peripheral surface of the organic fiber, wherein
- the fusion portion contains a second organic material and the inorganic particle, the second organic material having a melting point lower than a melting point of the first organic material.
