PROBLEM TO BE SOLVED: To provide an inspection method of a parameter having high correlation with tearableness of a split type optical fiber core tape consisting of a plurality of tape type optical fibers arranged in a parallel manner and coated with a connection coating layer, and each of the tape type optical fiber is structured by arranging a plurality of optical fibers in a parallel manner and coated with a bunch coating layer. SOLUTION: This invention includes a process (I) for cutting from a surface of the connection coating layer 22 to a boundary face between the connection coating layer 22 and the bunch coating layer 23 at predetermined rake angle and speed with a cutting edge 11, and a process (II) for moving the cutting edge 11 along the boundary face at a predetermined speed after the process (I) and peeling off the two coating layers 22 and 23 from each other. In the processes (I) and (II), the inspection method of degree of adhesion between the bunch coating layer 22 and the connection coating layer 23 measures a horizontal force generated on the cutting edge 11.
