A passage block formed with a passage connectable to a fluid control device comprises a first block member formed with a plurality of first-coupling-face apertures, a second block member formed with a plurality of second-coupling-face apertures in correspondence with the first-bonding-apertures, a first passage-end contact portion formed around each of the first-coupling-face apertures, a second passage-end contact portion formed around each of the second-coupling-face apertures, and a passage-end contact section provided in such a manner that a lower surface of the first block member and an upper surface of the second block member are arranged to face each other so that the first and second passage-end contact portions contact with each other, and the first and second block members are heated under pressure to diffusion-bond the first and second passage-end contact portions to each other.
