PROBLEM TO BE SOLVED: To provide a housing for an optical device capable of securely sealing the inside and preventing deterioration in properties of the optical device.SOLUTION: The housing for an optical device includes: a container portion 30 for storing an optical device 10 connected to optical fiber 11 while leading out the optical fiber 11 extending in a front-to-back direction, having side surfaces standing upward around a bottom surface 5 below, and including a slit 34 extending upward from below and opening upward, formed at one of front and rear side surfaces; a box-shaped lid member 20 opening downward, having a slit 24 extending downward from above and opening downward; and a tongue plate member 41 installed inside the container portion 30. The lid member 20 is fitted from the outside of the container portion 30, covering the whole side surfaces of the container portion 30. The slit 24 and the slit 34 form a rectangular opening for causing the inside and the outside of a housing 1a to communicate with each other, and leading out the optical fiber 11. The plate member 41 includes a slit 42 having such a width as to be in contact with the periphery of the optical fiber 11, and the plate member abuts an inner surface around the slit 24.SELECTED DRAWING: Figure 4 【課題】内部を確実に密封しつつ光デバイスの特性劣化を防止できる光デバイス用筐体を提供する。【解決手段】前後方向に延長する光ファイバ１１を外部に導出しつつ光ファイバ１１に接続された光デバイス１０を収納し、下方の底面５の周囲に上方に立設する側面を有し、前後いずれかの側面に下方から上方に向かって延長して開放するスリット３４が形成された容器部３０と、下方に開口する箱形で上方から下方に延長して開放するスリット２４が形成された蓋部材２０と、容器部３０の内方に設置される舌片状のプレート部材４１とを備え、蓋部材２０は容器部３０の外方から装着されて容器部３０の全側面を覆い、スリット２４とスリット３４により筐体１ａの内外を連絡して光ファイバ１１を導出するための矩形の開口部が形成され、プレート部材４１は光ファイバ１１の周囲に接する幅のスリット４２が形成されて、スリット２４の周囲内面に当接している。【選択図】図４
