Substrate (110) is disposed on a substrate, irradiating unit for irradiating a subject with light and (120) are disposed on the substrate, the light-emitting sensor device, from the subject due to the light emitted light receiving portion for detecting light (150), on the front side of the irradiation of the substrate is placed, the front plate is disposed so as to face the substrate (190), and irradiation unit as viewed in plan on the substrate and a bonding portion which comprise an adhesive for light protection is formed to surround each of the light receiving portion to bond together front plate and the substrate (180). Thus, suitable for mass production, it can be detected with high accuracy predetermined information type of blood flow velocity, etc. in the subject.自発光型センサ装置は、基板(110)と、基板上に配置され、光を被検体に照射する照射部(120)と、基板上に配置され、照射された光に起因する被検体からの光を検出する受光部(150)と、基板の照射部が配置された前面側に、基板に対向するように配置された前面板(190)と、基板上で平面的に見て照射部及び受光部の各々を取り囲むように形成されると共に遮光性の接着剤を含んでなり、基板及び前面板を互いに接着する接着部(180)とを備える。これにより、量産に適し、被検体における例えば血流速度等の所定種類の情報を高精度で検出可能となる。
