To provide an on-board camera device capable of confirming a temperature state of a window glass and a temperature state of a heater device by using a single temperature sensor, thereby contributing to a reduction in manufacturing costs.SOLUTION: An on-board camera device includes: a camera unit 10 configured to capture an image through a window glass 100; a hood member 12 configured to block an unnecessary light beam from outside of an imaging view of an imaging lens 11 and suppress background reflection on the window glass; a thermally conductive member 14 that is made of a highly thermally conductive material and fixed to an outer surface of the hood member to be in thermal contact with the window glass; a heater device 15 that is fixed in contact with an outer surface of the thermally conductive member and has a defogging function of removing dew condensation and fog adhering to a surface of the window glass at a front part of the camera unit; and a temperature measurement element 16 that is provided at a substantially center part of the heater device and has a portion that is disposed in contact with the thermally conductive member. The temperature measurement element is configured to: detect a temperature state of the heater device during operation of the heater device; and detect a temperature state of the window glass transmitted through the thermally conductive member during non-operation of the heater device.SELECTED DRAWING: Figure 4

    【課題】単一の温度センサで窓ガラスとヒータ装置の各温度状態を確認でき製造コストの低減化に寄与する車載カメラ装置を提供する。【解決手段】窓ガラス100越しの映像を撮像するカメラユニット10と、撮像レンズ11による撮像視野外からの不要光線を遮蔽すると共に窓ガラスへの映り込みを抑制するフード部材12と、熱伝導率の高い素材からなりフード部材の外表面に固定され窓ガラスに対して熱接触する熱伝導部材14と、熱伝導部材の外表面に接触して固定されカメラユニットの前方部分の窓ガラスの表面に付着した結露や曇りを除去する防曇機能を有するヒータ装置15と、ヒータ装置の略中心部分に設けられ一部が熱伝導部材に接触して配設された温度測定素子16とを具備し、温度測定素子は、ヒータ装置の作動時にはヒータ装置の温度状態を検出し、ヒータ装置の非作動時には熱伝導部材を通じて伝達される窓ガラスの温度状態を検出する。【選択図】図4
