PROBLEM TO BE SOLVED: To provide a sheet for circuit board with which a circuit board where a circuit chip is buried for controlling respective pixels for display can efficiently be manufactured with sufficient quality and high productivity, and to provide the chip buried circuit board. SOLUTION: The sheet for circuit board is formed of an energy line curing polymeric material for burying the circuit chip. A plurality of recessed grooves opened to both ends are formed on a surface of a side where the circuit chip is buried in a non-curing layer formed of the energy line curing polymeric material. In the chip buried circuit board, the circuit chip is buried in the non-curing layer formed of the energy line curing polymeric material in the sheet for circuit board, and the chip is irradiated with an energy line so as to cure it.
