PROBLEM TO BE SOLVED: To measure the transparency of the skin by a miniaturized device structure without being affected by the reflection light on the surface of the skin or the ambient light.SOLUTION: The transparency measuring device is used in contact with the surface of the skin. The transparency measuring device includes a light projecting part 2 having an LED 20 for emitting light of a prescribed wavelength for projecting the light from the LED 20 to the skin surface, and an imaging part 3 for capturing the image of the skin surface in a place different from where the light is projected but a place where the projected light is diffused inside. The light projecting part 2 has an opening 24 to be brought into contact with the skin surface, and the direct light from the LED 20 is shaded as the opening 24 is brought into contact with the skin surface.COPYRIGHT: (C)2011,JPO&INPIT【課題】肌の表面反射光あるいは外乱光などの影響を受けることなく肌の透明感を小型化された装置構成により測定すること。【解決手段】皮膚表面に接触させて用いられる透明感測定装置において、所定の波長の光を照射するLED20を有し、LED20からの光を皮膚表面に投光する投光部2と、光が投光された皮膚表面とは異なる場所であって、投光された光が内部で拡散している場所の皮膚表面を撮像する撮像部3とを有し、投光部2は、皮膚表面に接触する開口部24を有し、開口部24が皮膚表面に接触することで、LED20からの直接光が遮光されるようにする。【選択図】図4
