There is provided an electromagnetic inductive encoder that allows reduction in the number of tracks on a scale for reduction in the size of the scale. The electromagnetic inductive encoder includes a scale having a scale pattern, a head, and computation unit. The head includes transmission unit, which includes transmission coils, and reception unit, which includes reception coils. The scale pattern has a first pattern, which causes the reception coils to receive positive current, and a second pattern, which causes the reception coils to receive negative current. The computation unit includes a determination unit, which, when the positive current is detected, determines that the current is associated with the first pattern, and, when the negative current is detected, determines that the current is associated with the second pattern, a signal generation unit, which generates a signal formed of “1” representing the first pattern and “0” representing the second pattern based on the result of the determination, and a position calculation unit, which calculates the position of the head based on the signal generated by the signal generation unit.
