The fluid control apparatus includes fluid control units to control a flow rate or pressure of a fluid, an electric circuit board to send and receive a signal to and from the fluid control units, a casing to accommodate therein the fluid control units and the electric circuit board, and an apparatus-side connector interposed between the electric circuit board and a cable electrically connected thereto. The fluid control apparatus further includes a connector board configured to mount thereon the apparatus-side connector. The connector board is secured to the electric circuit board with at least a part of the connector board in surface contact with the electric circuit board, or overlapping the electric circuit board with a clearance therebetween. ## Claims ### Claim 1 A fluid control apparatus, comprising: a fluid control unit configured to measure a flow rate or pressure of a fluid; a circuit board configured to send and receive a signal to and from the fluid control unit; a casing configured to accommodate therein the fluid control unit and the circuit board; and an apparatus-side connector configured to accept connection from a cable, wherein the fluid control apparatus further comprises, besides the circuit board, a connector board configured to mount thereon the apparatus-side connector, and wherein the connector board is secured to the circuit board in a state in which at least a part of the connector board is overlapped with the circuit board. ### Claim 2 (depends on 1) The fluid control apparatus according to claim 1, wherein a surface of the connector board opposed to the circuit board is a mount surface configured to mount thereon the apparatus-side connector. ### Claim 3 (depends on 2) The fluid control apparatus according to claim 2, wherein an electronic component is mounted on the mount surface of the connector board. ### Claim 4 (depends on 1) The fluid control apparatus according to claim 1, wherein the connector board is in surface contact with the circuit board. ### Claim 5 (depends on 1) The fluid control apparatus according to claim 1, wherein the circuit board comprises a notch part configured to dispose at least a part of the apparatus-side connector, and wherein the connector board is disposed so as to cover the notch part. ### Claim 6 (depends on 1) The fluid control apparatus according to claim 1, wherein one of the circuit board and the connector board comprises an end-surface through hole disposed at a position along an outer peripheral part of one of the circuit board and the connector board, and the one is overlapped with another at the position, and wherein the another of the circuit board and the connector board comprises a connection terminal part disposed at a position corresponding to the end-surface through hole. ### Claim 7 (depends on 1) The fluid control apparatus according to claim 1, wherein a width dimension of the casing is 10 mm or less. ### Claim 8 A fluid control apparatus, comprising: a fluid control unit configured to measure a flow rate or pressure of a fluid; a circuit board configured to send and receive a signal to and from the fluid control unit; a casing configured to accommodate therein the fluid control unit and the circuit board; and an apparatus-side connector configured to accept connection from a cable, wherein the fluid control apparatus further comprises, besides the circuit board, a connector board configured to mount thereon the apparatus-side connector, and wherein the connector board is disposed in the casing so that a cable-side connector being connected to the apparatus-side connector is accommodated within a width of the casing.
