PURPOSE: An adhesion tester is provided to perform adhesion test for the sample like rubber composition in a convenient and accurate manner, while achieving improved portability. CONSTITUTION: An inverse-trapezoidal funnel(5) having tilt surfaces(4a,4b) formed at both sides of the funnel, is installed onto a support board(3). The support board has a horizontality adjusting scale(1) disposed onto the support board and horizontality adjusting support legs(2) disposed at each corner of the lower surface of the support board. A rubber composition sample(7) is attached to a bottom surface of the funnel, and the funnel has scale rulers(8) printed at both inner side surfaces of the funnel. The tilt surface(4a) of the funnel has a ball firing part(11) having a semi-arc shaped groove(10) and which is elastically supported by a spring(9).
