<p>PROBLEM TO BE SOLVED: To provide a photoelectric conversion module which does not easily interfere with an electromagnetic wave from outside and has the emission of an electromagnetic wave from itself to a degree free from causing a trouble in practical use, and to provide an electric circuit forming an inductance element and (or) a capacitance element by providing a circuit pattern on an electronic circuit board. SOLUTION: A photoelectric conversion module is obtained by arranging a component consisting of a light emitting element 2, a light receiving element 3 and a driver IC4 for driving these elements on the surface of an electric circuit substrate 1. The whole component except for the path of light is covered with a shielding case 5, the electronic circuit substrate is made from electromagnetic wave absorption material 52 obtained by diffusing soft magnetic material powder in the matrix of synthetic resin, and the shielding case is made from electromagnetic wave absorption material obtained by diffusing soft magnetic material powder in the matrix of synthetic resin on both of the sides of a foil made of soft magnetic metal. The electric circuit consisting of the inductance element and the capacitance element is formed on the electronic circuit board.</p> |
