<p>PROBLEM TO BE SOLVED: To fill up a case with a resin in a short time in a proximity sensor. SOLUTION: A groove for discharging air is formed in a coil case 7 provided on a front surface of a proximity sensor. An aperture 43 is provided at a clamp part 9 to hold a cord 10 on the back side of a base metal 8. The proximity sensor 1 is kept at a low pressure, and a resin is injected from the aperture 43 at the clamp part 9, thereby the resin can be filled into the case 7 in a short time.</p> |
