Summary:To provide an electronic component that can prevent stray light from being emitted to the outside.SOLUTION: An electronic component 1 comprises a lid part 2, a substrate 3, and a light deflector 4, and the under surface of the lid part 2 and a wiring layer 8 on the substrate 3 are joined to form a junction 5. The lid part 2 covers a reflection surface side of a rotary mirror part 10 of the light deflector 4, and is provided on the top plate with an aperture plate 6 through which incident light is transmitted. The substrate 3 is mounted with the light deflector 4, is provided with the wiring layer 8 having wires connected to electrodes of the light deflector 4, and has a curved surface-like concave part 31 on the back side of the light deflector 4. The light deflector 4 is arranged at a position where the rear face of the rotary mirror part 10 is irradiated with light reflected on the concave part 31.SELECTED DRAWING: Figure 2 【課題】迷光が外部に放出されることを防止することができる電子部品を提供する。【解決手段】電子部品１は、リッド部２と、基板３と、光偏向器４とを備え、接合部５は、リッド部２の下面と基板３上の配線層８とが接合されてなる。リッド部２は、光偏向器４の回動ミラー部１０の反射面側を覆い、天板に入射光が透過する窓板６が設けられている。基板３は、光偏向器４が載置され、光偏向器４の電極に接続された配線を有する配線層８が設けられ、光偏向器４の裏面側に曲面状の凹部３１を有している。光偏向器４は、凹部３１で反射された光が回動ミラー部１０の裏面に照射される位置に配置されている。【選択図】図２
