<P>PROBLEM TO BE SOLVED: To provide a reflection-type photoelectric sensor with high sensitivity and reliability by preventing outflow of an adhesive. <P>SOLUTION: A reflection-type photoelectric sensor comprises: a light-emitting element 3; a projection lens 1 provided in front of the light-emitting element 3; a light-receiving element 4 for receiving light from the light-emitting element 3; a light-receiving lens 2 provided in front of the light-receiving element 4; a main circuit 5 for performing signal processing on the basis of an output signal from the light-receiving element 4; and a structure 6 to which at least one of the projection lens 1 and the light-receiving lens 2 is fixed with an adhesive. The structure 6 has a supply section 11 for supplying the adhesive to a connection section and a guide section 6g for guiding the adhesive supplied from the supply section 11 to the connection section so as to prevent outflow of the adhesive. <P>COPYRIGHT: (C)2012,JPO&INPIT |
