To downsize a fluid controlling apparatus, as a structure capable of greatly reducing width direction dimensions as compared with a conventional one without deteriorating pressure measurement sensitivity, and capable of reducing the width direction dimensions of a casing while ensuring the mechanical strength of the casing.
A fluid controlling apparatus includes a body unit 1, a fluid control valve 4, pressure sensors 2A and 2B, and a casing 7. The fluid control valve 4 is attached to a component installation surface 1x of the body unit 1, and the pressure sensors 2A and 2B are attached to the component installation surface 1x so as to make a pressure-sensitive surface 2b1 become generally vertical to the component installation surface 1x and generally parallel in a longitudinal direction. On side walls 7a and 7b of the casing, an inner surface is made to have a recessed/projecting shape. Parts opposing to the fluid control valve 4 and the pressure sensors 2A and 2B are made to be thin-wall portions P1-P3, and at least a part of parts which do not oppose to the fluid control valve 4 and the pressure sensors 2A and 2B are made to be thick-wall portions Q1 thicker than the thin-wall portions P1-P3.
