To provide a chemical solution supply device capable of inserting a needle into the skin while reducing pain and capable of reliably supplying a chemical solution to the skin. A chemical supply apparatus includes a substantially cylindrical base, a needle holding member disposed in a central opening of the base so as to be movable in the axial direction of the base, and a needle holding member. And a cap 8 disposed so as to be movable in the axial direction of the base 4. A needle 9 projects from the skin side surface of the needle holding member 6, a first spring 13 is disposed between the base 4 and the needle holding member 6, and a second spring is provided between the cap 8 and the needle holding member 6. A spring 24 is provided, and a fitting rib 42 is formed on the cap 8 so that the needle holding member 6 can move in the axial direction and cannot rotate in the rotational direction. The accommodating portion 30 is formed, and the needle holding member 6 is formed with a through hole 31 that can supply a chemical solution onto the skin. [Selection] Figure 1 |
