Titanium Laminate, and Method for Producing Titanium Laminate

Abstract

A titanium laminate according to this invention is in sheet form and includes a plurality of titanium gas-liquid permeable layers, each having pores through which a gas and/or a liquid can pass, the gas-liquid permeable layers being laminated by bonding adjacent titanium bonding surfaces together in a lamination direction, wherein at least the gas-liquid permeable layer forming one laminate surface of the plurality of gas-liquid permeable layers is a porous layer having a thickness of 500 μm or less, and wherein, on the one laminate surface, an average value of areas of pores opening to the laminate surface is 4 μm2 or more and 17 μm2 or less, a standard deviation value of the areas of the pores is 20 μm2 or less, and a number of pores present within a rectangular region having an area of 22 000 μm2 and an aspect ratio of 4:3 is 120 or more, and wherein, on the other laminate surface located on a back side of the one laminate surface, an average value of areas of pores opening to the laminate surface is three times or more the average value of the areas of the pores opening to the one laminate surface.
