It is intended to provide a microneedle and a microneedle array comprising an auto-soluble base and capable of realizing higher absorptivity and pharmacological effect. A preparation for application to the body surface 1 has two portions divided in an insertion direction, i.e., a fore-end portion 5 and a rear-end portion 6. The fore-end portion 5 includes a body surface insertion end 2 and holds a base-soluble target substance. The rear-end portion 6 includes a pressing end 3 and is mainly constituted by only a base and does not hold a target substance. When the preparation for application to the body surface 1 is inserted into the body surface such as the skin, even if a portion of the rear end side is not inserted into the body surface and remains outside, an actual given dose of the target substance is not less than a desired amount because the target substance is contained in the fore-end portion 5, and a high absorptivity and pharmacological effect can be realized.
