PROBLEM TO BE SOLVED: To provide a source driver increasing a heat radiating quantity, and also to provide a liquid crystal module. SOLUTION: The film mounted type source driver 100 is provided with: a semiconductor chip 105 having a plurality of connectable terminals with the outside are mounted on the surfaces of a film forming base material 107; an input terminal wiring region 101 having formed wiring connected with the input terminals of the semiconductor chip 105; an output terminal wiring region 102 having wiring connected with the output terminals of the semiconductor chip 105 are provided. Sprocket portions 103 each having a continuous hole sequence 106 and a copper foil formed on its surface are provided at both ends of the film forming base material 107, and the input terminal wiring region 101 and the output terminal wiring region 102 are so provided in opposite directions of each other as to be extended toward the side with no sprocket portion 103, and a thermal conduction pattern 104 for connecting the terminals of the semiconductor chip 105 except its input and output terminals with the copper foils of the sprocket portions 103 is formed.
