Provided are a sealing tape that can prevent tape width misalignment, air bubble inclusion, and creasing even when the sealing tape is affixed in a folded state, a phosphor sheet using the same, a lighting device, a liquid-crystal display, a method for manufacturing a phosphor sheet, and a sealing method. The sealing tape (10) includes an adhesive layer (11), a gas barrier layer (12), a bonding layer (13), and a support film layer (14) laminated in stated order, and has an incision (15) into the support film layer (14) in a thickness direction. The incision (15) is located substantially centrally in a width direction and extends in a longitudinal direction. Accordingly, tape width misalignment, air bubble inclusion, and creasing can be prevented even when the sealing tape is affixed in a folded state.

A heat diffusion sheet includes a graphite sheet having a thickness of from 20 μm to 80 μm, an acrylic adhesive layer having a thickness within a range of from 5 μm to 15 μm and not containing a thermally conductive material, a polyester film having a thickness within a range of from 5 μm to 30 μm, and a silicone adhesive layer thinner than the polyester film, having a thickness within a range of from 2 μm to 25 μm, not containing a thermally conductive material and having a peeling strength of from 0.005 N/cm to 1.0 N/cm, sequentially laminated from the graphite sheet. Heat generated by the object to which the silicone adhesive layer is to be adhered is easily transferred to the graphite sheet and the heat diffusion sheet can be peeled off and reused easily.

A heat diffusion sheet 2 has a configuration in which a composite adhesive film is formed on a surface of a graphite sheet 10 having a thickness of 300 μm or more and 2,000 μm or less. This composite adhesive film has a configuration in which (A) an acrylic adhesive layer that has a thickness of 5 μm or more and 15 μm or less and does not contain a thermally conductive material, (B) a polyester film having a thickness of 20 μm or more and 60 μm or less, and (C) a silicone adhesive layer that has a thickness of 2 μm or more and 25 μm or less, does not contain a thermally conductive material, and has a peel strength of 0.005 N/cm or more and 1.0 N/cm or less are sequentially layered on the graphite sheet 10.
