PROBLEM TO BE SOLVED: To provide a continuous heat treatment furnace capable of performing mass heat treatment for a comparatively long time by extending a residence time in the heat treatment furnace without extending a horizontal length of the heat treatment furnace and without changing a conveyance speed on the outside of the heat treatment furnace.SOLUTION: The continuous heat treatment furnace includes: a carrying part (carrying conveyor 15) for successively carrying laid plate-like objects 100 to be treated from the outside of the furnace 1 to the inside of the furnace 1; a vertical conveying passage (intra-furnace conveying means 5) for successively receiving the plate-like objects 100 to be treated in the furnace, holding the laid objects 100 to be treated on multiple stages in the vertical direction, and conveying the held objects 100 to be treated upward or downward in the furnace; and a carry-out part (carry-out conveyor 16) for successively receiving plate-like objects 100 to be heat treated while being conveyed through the vertical conveying passage on an upper position or a lower position in the conveyance direction and successively carrying out the received objects 100 to the outside of the processing furnace, so that heat treatment can be efficiently performed for a long time without extending the furnace length.
