The present invention relates to a straight-pipe-type light emitting diode (LED) lighting lamp which has improved heat-dissipation and optical characteristics. A straight-pipe-type LED lighting lamp according to the present invention comprises: a circuit board on which a plurality of LEDs are disposed; a heat-dissipating portion which has a connection groove for connection and a circuit board accommodation part accommodating the circuit board; a cover portion which has a connection protrusion connected with the connection groove of the heat-dissipating portion; and a circuit board compression portion which is branched from the inside surface of the cover portion, and, when the heat-dissipating portion and the cover portion are connected, compresses the circuit board toward the circuit board accommodation part to make the circuit board closely adhere to the heat-dissipating portion.
