Abstract: A fluid control device for mixing liquids, includes at least: a monolithic base body; and a plurality of micro holes disposed in the base body. Also, the micro holes in a flow channel group α that configures a specific group have opening portions in a region A and a region B on surfaces being outer surfaces of the base body, the micro holes in a flow channel group β (n) that configures the other specific group have opening portions in the region A and a region C (n) on the surfaces being outer surfaces of the base body, and in the base body, the micro holes are disposed apart from the micro holes belonging to the different flow channel group throughout entire lengths. Here, the n refers to a natural number.

Abstract: A differential pressure detection element includes: a support portion having an opening; a cantilever portion supported in a cantilever manner by the support portion so as to protrude into the opening; a diffusion layer including a piezoresistive portion provided at a fixed end of the cantilever portion; a pair of wiring portions electrically connected to the diffusion layer; a first insulating layer covering the diffusion layer; and a second insulating layer laid on the first insulating layer. A linear expansion coefficient of the first insulating layer is smaller than a linear expansion coefficient of a material of which the cantilever portion is composed, and a linear expansion coefficient of the second insulating layer is larger than the linear expansion coefficient of the first insulating layer.
