Summary:To provide a connection structure capable of connecting a plurality of light guide bodies in portions other than end faces.SOLUTION: A first light guide body 20 and a second light guide body 30 respectively comprise refraction control parts 27 and 37 for emitting propagated light in a light emission direction L in a portion of side faces. The first light guide body 20 comprises a first connection part 22 which is bent in a first direction as being closer to one end, and the second light guide body 30 comprises a second connection part 32 which is bent in a second direction as being closer to the other end. The first light guide body 20 and the second light guide body 30 are connected in the first connection part 22 and the second connection part 32 in such a manner that the first connection part 22 is disposed at a side of the first direction and that the second connection part 32 is disposed at a side of the second direction. A connection plane 42 is configured in the light emission direction L to form an angle for suppressing leakage of light propagated inside of the first light guide body 20 and the second light guide body 30 with respect to a length direction.SELECTED DRAWING: Figure 3 【課題】複数の導光体を端面以外の部分で接続することができる接続構造の提供【解決手段】第１導光体２０および第２導光体３０はそれぞれ、側面の一部に、伝播した光を出光方向Ｌに沿って出光させるための屈折制御部２７，３７を有し、第１導光体２０は、一方の端部に近づくにつれて第１方向に向けて屈曲された第１接続部２２を備え、第２導光体３０は、他方の端部に近づくにつれて第２方向に向けて屈曲された第２接続部３２を備え、第１導光体２０と第２導光体３０とは、第１接続部２２が第１方向の側に配され、第２接続部３２が第２方向の側に配されるかたちで第１接続部２２と第２接続部３２とにおいて接続されており、接続面４２は、出光方向Ｌに沿うとともに、長さ方向に対して、第１導光体２０と第２導光体３０の内部を伝播する光の漏出を抑制する角度をなす構成を備えている。【選択図】図３
