PROBLEM TO BE SOLVED: To prevent an inflow of grease to a zone of a fixed contact of a push switch. SOLUTION: In a grease inflow preventing structure in a printed circuit board 10 wherein a fixed contact 20 of a slide switch and the fixed contact 30 of the push switch are arranged on the same surface of the printed circuit board 10 and grease is applied to a grease application zone G including the fixed contact 20 of the slide switch, a partition hole 13 for partitioning a zone of the fixed contact 20 of the slide switch and a zone of the fixed contact 30 of the push switch is arranged on the printed circuit board 10, a rib 45 arranged at a position of a rubber containing sheet 40 mounted on the printed circuit board 10 corresponding to the partition hole 13 is insertion-fitted into the partition hole 13, and thus, a movement of grease from the grease application zone G to the fixed contact 30 of the push switch can be prevented with the rib 45 and the partition hole 13.
