ABSTRACT:
A chemical analysis slide includes at least two plastic sheets superposed one on another and bonded together, and a chemical analysis film sandwiched therebetween. In a method of continuously assembling such chemical analysis slides, while at least two plastic sheets in continous lengths are conveyed in the longitudinal direction thereof, a plurality of chemical anaylsis films are sandwiched between the plastic sheets at predetermined intervals, the plastic sheets are bonded together at a portion circumscribing each of the chemical analysis films sandwiched therebetween to form a sheet assembly and individual chemical analysis slides are cut out from the sheet assembly. At least one of the sheets in continuous lengths is provided with a plurality of slits extending in the transverse direction of the sheet at regular intervals at the remaining portions of the sheet which do not form a part of the chemical analysis slide.
