PROBLEM TO BE SOLVED: To provide a logic plate for completely preventing the leakage of fluid while sufficiently securing the passage sectional area of a fluid passage, when used for controlling high pressure fluid whose pressure reaches 20-30MPa. SOLUTION: The high pressure fluid logic plate comprises a grooved plate member having a groove and a cover plate member covering the groove to form a closed passage. The cover plate member is joined along the groove of the grooved plate member, and a reinforcing member is mounted on the upper face of the cover plate member with a connection means. To obtain a two-layer high pressure fluid logic plate, the cover plate members of the logic plates each of which has the grooved plate member having the groove and the cover plate member covering the groove to form the closed passage are fitted and connected to each other. Furthermore, to obtain a multi-layer high pressure fluid logic plate without the need for the reinforcing plate member, the cover plate member of the logic plate which has the grooved plate member having the groove and the cover member covering the groove to form the closed passage are fitted and connected to the back face of the grooved plate member of the two-layer logic plate.
