PURPOSE: A flat plate type of a solar collector is provided to improve the efficiency of collecting heat, and to easily connect a connection pip to an external pipe. CONSTITUTION: A flat plate type of a solar collector comprises a transparent plate(10), a heat collection plate(20), a lower plate(30), and a connection pipe. Sunlight penetrates through the transparent plate, and the transparent plate has an insulation function. The heat collection plate is installed under the transparent plate, and a main pipe unit linked to a branch pipe unit heats fluid by the sunlight. The heat collection plate is formed by joining two heat collection boards facing each other so that the main and branch pipe units(22,24) where the fluid flows are formed. The lower plate is installed under the heat collection plate, and has an insulation function. The connection pipe is linked to the lower part of the main pipe unit of the heat collection plate in order to be connected to an external pipe.
