A fluidic device includes a planar structure constituted by a plurality of laminated layers and accommodating a fluid channel extending up to a surface of the planar structure, and a female adapter piece configured for a fluid-tight accommodation of a male adapter piece having a fluid conduit. The the female adapter piece is connected or connectable with the planar structure so that, when the male adapter piece is accommodated in the female adapter piece, the fluid conduit is brought in fluid-tight fluid communication with the fluid channel. The fluid channel is exposed to the female adapter piece at a lateral surface of the planar structure at which the laminated layers are exposed.
