Abstract:
A drive circuit for driving a semiconductor light emitting element includes a board, a first pattern formed in a first layer of the board so as to be electrically connected to an anode of the semiconductor light emitting element, and a second pattern formed in a second layer of the board so as to be electrically connected to a cathode of the semiconductor light emitting element, and the first pattern and the second pattern are formed so as to overlap with each other when viewed in a direction along a normal line of the board.
