A photoelectric encoder (1) according to the present invention comprises a light-receiving unit (7) including: a first and second light-receiving element column (LRL); and a light-blocking layer (20) configured from a light-blocking portion (20a) and a light-transmittingportion (20b), the first and second light-receiving element columns being disposed staggered in a second direction such that an arrangement pattern of light-receiving elements in the first and second light-receiving element columns has a pitch which is the same in a first direction and a phase which differs in the first direction, and the light-transmitting portion on the light-receiving surface of the light-receiving element in the first light-receiving element column and the light-transmitting portion on the light-receiving surface of the light-receiving element in the second light-receiving element column being formed so as not to overlap each other when staggered in the second direction. |
