Claim:
A light emitting device comprising: an insulating board having a mounting surface, a front surface, and a rear surface, both the front surface and the rear surface being substantially perpendicular to the mounting surface; a first conductor pattern having a cathode electrode and an anode electrode formed on the front surface of the insulating board, and the first conductor pattern extending substantially to the mounting surface on at least one of the front surface and the rear surface of the insulating board so as to be exposed close to the mounting surface for receiving a power supply; at least one second conductor pattern having a cathode electrode and an anode electrode formed on the front surface of the insulating board, and the at least one second conductor pattern extending substantially to the mounting surface on at least one of the front surface and the rear surface of the insulating board so as to be exposed close to the mounting surface for receiving a power supply; a first LED chip having an electrostatic breakdown voltage and mounted on the front surface of the insulating board, the first LED chip including a cathode and an anode and being a red LED chip that is composed of an AlGaInP-based compound semiconductor, and the cathode of the first LED chip electrically connected to the cathode electrode of the first conductor pattern, and the anode of the first LED chip electrically connected to the anode electrode of the first conductor pattern; at least one second LED chip having an electrostatic breakdown voltage and mounted on the front surface of the insulating board, the at least one second LED chip including a cathode and an anode and being at least one of a blue LED chip and a green LED chip that are composed of an GaN-based compound semiconductor, the cathode of the at least one second LED chip electrically connected connected to the cathode electrode of the at least one second conductor pattern, and the anode of the at least one second LED chip electrically connected to the anode electrode of the at least one second conductor pattern; and an encapsulating resin located so as to encapsulate both the first LED chip and the at least one second LED chip on the front surface of the insulating board, wherein the electrostatic breakdown voltage of the first LED chip is higher than the electrostatic breakdown voltage of the at least one second LED chip, and at least part of one electrode of the first conductor pattern is located at a position that is further from the mounting surface of the insulating board than a portion of the at least one second conductor pattern that is furthest, relative to all other portions of the at least one second conductor pattern, from the mounting surface of the insulating board.
