A laminating apparatus for improving the uniformity of the thickness of a resulting laminate to improve the yield of products such as laminates is provided. A pressing device includes: a first press block movable back and forth; a second press block disposed in opposed relation to the first press block; a first pressing plate mounted to the inside of the first press block; and a second pressing plate mounted to the inside of the second press block. The first pressing plate and the second pressing plate are opposed to each other. A surface of the first pressing plate which is opposed to the second pressing plate has a peripheral portion formed into a tapered surface in such a manner that the distance from the second pressing plate increases in an outward direction.
