PROBLEM TO BE SOLVED: To provide a cylinder discrimination device, in which a size of a signal plate of a can sensor outputting a cylinder discrimination signal of an engine can be reduced, and a setting degree of freedom of the number of the cylinder discrimination signal is high. SOLUTION: In a series four-cylinder engine having an intake side camshaft and an exhaust side camshaft, a first and a second cam sensors respectively outputting the cylinder signal discrimination signals Phase 1, Phase 2 are disposed to the intake side camshaft and the exhaust side camshaft, respectively. The number of outputs of the cylinder signal discrimination signals Phase, Phase 2 are counted between reference crank angle positions detected as missing of position signals POS to carry out a cylinder discrimination based on combination patterns of the number of the output of the cylinder signal discrimination signals Phase 1, Phase 2.
