<P>PROBLEM TO BE SOLVED: To provide a light transmitting/receiving module with a structure capable of suppressing interference between transmitting and receiving sides, even in the case of some clearance in the array of shielding walls; and capable of expecting the same effect as complete arrangement of shielding walls between the transmitting and the receiving sides without any lacks in array, even in the case that some walls are set structurally absent in spite of initial design concept of full arrangement. <P>SOLUTION: Result which is equivalent to that in a state wherein a wall does not lack can be obtained by sticking a wave absorber 106 to a part which lacks in cases 104, 107 with a shielding wall 105 which partially lacks because of a structural problem. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
