Abstract: A transdermal absorption-type patch (10) includes: a support material (1) and an adhesive layer (2) laminated on the support material (1). The adhesive layer (2) includes: a solid composite material (2a), the solid composite material (2a) being an active ingredient with a molecular weight of 800 or greater enclosed by a surfactant; an oil phase; and an adhesive agent, the adhesive agent containing an acrylic elastomer. The content of the acrylic elastomer is 30% to 70% by mass based on the total mass of the acrylic elastomer and the oil phase. The composite material (2a) forms a solid-in-oil type particle dispersed in the oil phase.
