Provided is an LED bulb lamp. A lamp cap, a lamp cap connecting piece, a radiator, a fixing ring and a lampshade are connected in sequence. A first containing cavity is formed by connecting the radiator, the fixing ring and the lampshade. A lamp wick, a substrate and LED lamp beads are contained in the first containing cavity. One end of the lamp wick is connected with the radiator. The side wall of the lamp wick is provided with a plurality of grooves and a plurality of positioning columns. The substrate comprises a panel and a plurality of side plates. The number of edges of the panel is the same with the number of the side plates. A positioning groove is formed between every two adjacent side plates. The LED lamp beads are arranged on the surface of the panel and the surfaces of the side plates. The substrate is installed on the lamp wick. A second containing cavity is formed by connecting the lamp cap connecting piece with the radiator. An LED power source is contained in the second containing cavity and electrically connected with the lamp wick. After the LED bulb lamp is turned on, the LED lamp beads located on the substrate emit light rays to the side surfaces and the end surface, so that light rays are evenly distributed and are not likely to be converged on one point, and the luminance uniformity of the LED bulb lamp is improved.
