To enable a small imaging device to easily reduce variations in focus caused by temperature change.SOLUTION: An imaging device includes: a lens barrel that holds a plurality of lenses 104a and 104b; an imaging element 115 that images an object through the plurality of lenses; and a holding member 105 that holds the imaging element and the lens barrel. The lens barrel is configured by combining a plurality of partial lens barrels 101 and 102 that respectively holds the lenses. The holding member holds any among the plurality of partial lens barrels in a holding section 108 further toward the object than the lens, closest to an image side, among the plurality of lenses. A linear expansion coefficient of at least one partial lens barrel among the plurality of partial lens barrels is different from linear expansion coefficients of the other partial lens barrels.SELECTED DRAWING: Figure 1

    【課題】小型の撮像装置において、容易に温度変化に伴うピント変動を低減可能とする。【解決手段】撮像装置は、複数のレンズ104a,104bを保持する鏡筒と、複数のレンズを介して物体を撮像する撮像素子115と、撮像素子および鏡筒を保持する保持部材105とを有する。鏡筒は、それぞれレンズを保持する複数の部分鏡筒101,102が結合されて構成されている。保持部材は、複数のレンズのうち最も像側のレンズよりも物体側の保持部108において複数の部分鏡筒のうちいずれかを保持している。複数の部分鏡筒のうち少なくとも1つの部分鏡筒の線膨張係数が他の部分鏡筒の線膨張係数と異なる。【選択図】図1
