<P>PROBLEM TO BE SOLVED: To provide an illumination sheet in which a light receiving part of a light guide sheet can be fixed certainly to an optimal position near the light source part of a circuit board. <P>SOLUTION: The illumination sheet includes: a light guide sheet which guides light and emits it from a first plane; and a carrier sheet 3 which is adhered to the first plane and suppresses bending of the light guide sheet. The light guide sheet has an adhesion part 23 which enables adhesion of the light guide sheet to the circuit board in the vicinity of a first side face crossing at right angles the first plane and a second plane on the second plane opposed to the first plane. The carrier sheet 3 is provided with a cut part 5 which is cut out in the longitudinal direction of the first side face and in the thickness direction of the carrier sheet 3, a first slit part 7 which is cut in a direction connecting a first portion 31a of a second side face 31 of the carrier sheet 3 located on the opposite side to the adhesion part 23 of the cut part 5 with the cut part 5, and a second slit part 8 which is cut in a direction connecting a second portion 31b of the second side face 31 with a prescribed spacing from the first portion 31a with the cut part 5. <P>COPYRIGHT: (C)2010,JPO&INPIT |
