To provide a connection structure for an integrated panel and fluid device capable of miniaturizing in order to promote integration of fluid piping.

In the concentric double fluid fluid type connection structure in which tubular fluid passages 3a and 7 and annular fluid passages 4a and 8 are arranged in a concentric state and the integrated pane 1 and a valve 2 are connected in a sealed state via inner and outer annular gaskets G1 and G2, annular projections 11, 21, 31, and 41 are formed on fluid inlet and outlet sections 1A and 2A made of a resin material, and annular grooves 51 and 61 are formed on the gaskets G1 and G2 made of a fluorocarbon resin material. A joining state forming a fitting seal section 10 by fitting the annular projections and grooves is maintained by a maintaining means for maintaining by pulling near both fluid inlet and outlet sections 1A and 2A. An inner peripheral surface 54a of the first gasket G1 at an inner side serves as an external wall surface of the tubular passages 3a and 7, and its outer peripheral surface 55a is prepared for a multifunctional middle gasket which also serves as an inner peripheral wall surface of the annular fluid passages 4a and 8.
