1. A puncture device for puncturing skin with a puncture needle, the puncture device comprising:
- retaining means for holding the puncture needle;
a fixing portion movably supporting the retaining means and possessing a flat contact surface to be fixed to a body surface;
a positioning portion to which the fixing portion is rotatably connected and which possesses a flat surface to be fixed to the body surface;
wherein in a state in which the positioning portion is fixed to the body surface, the fixing portion is configured to be rotated from a position where the flat contact surface of the fixing portion is approximately orthogonal to the flat surface of the positioning portion toward a body surface side to raise the skin of the body surface where the flat surface of the positioning portion is fixed; and
the retaining means being configured to be moved to puncture the raised skin with the puncture needle passing through an opening window provided at an end of a positioning portion side part of the fixing portion.

7. A puncture device comprising:
-
a puncture needle for puncturing a skin outer surface and entering a first section of a predetermined inner layer of said skin, a needle moving device carrying said puncture needle for movement therewith, a puncture needle guiding portion for guiding movement of said needle moving device and said puncture needle along a needle path; and a skin deforming portion including a skin depressing surface rigid with said needle guiding portion and arranged for downwardly depressing and deforming a second section of said predetermined inner layer disposed adjacent to said first section, such that the downward deformation of said second section uplifts said first section and produces a step in a portion of said skin outer surface disposed between said first and second sections, which step faces a tip of said needle; wherein said needle moving device and said puncture needle are guided in movement by said puncture needle guiding portion to cause said puncture needle to puncture said step and enter said first section of said predetermined skin layer in a direction parallel to said skin depressing surface.
