A micro flow passage device in which a flow passage wall has high hydrophobicity and high cracking resistance is provided. In the micro flow passage device, a flow passage interposed between a flow passage wall is formed in the interior of a porous substrate, a flow-passage-wall-forming material constituting the flow passage wall contains a thermoplastic resin and a wax, X<Y where an abundance ratio of the wax in the flow passage wall on the surface side of the porous substrate is denoted by X, and an abundance ratio of the wax present in a pore in the interior of the porous substrate is denoted by Y, a content of the wax is 13.1% to 70.0% by mass, and SP(B)−SP(W)≥0.6 where an SP value of the wax is denoted by SP(W), and an SP value of the thermoplastic resin is denoted by SP(B).
