To suppress positional deviation of a wayside coil substrate 10, prevent deterioration in yield, and prevent deterioration in water proof property and vibration resistance of a wayside coil 1 when making a resin outer shell 40 by covering the wayside coil substrate 10 by a resin mold sheet (for example, SMC sheets 41, 42) and compression molding by press molding.SOLUTION: Compression molding is carried out by using positioning pins 56 projected toward one mold of either an upper die 51 or a lower die 52 for press molding from at least two positions (for example, from four corners of a rectangular substrate) of the wayside coil substrate 10 and in a state with each positioning pin 56 inserted in positioning holes 55 provided on one of the molds (preferably the lower die 52).SELECTED DRAWING: Figure 4
【課題】地上子基板10を樹脂成形用シート(例えばSMCシート41,42)で覆い、プレス成形によって圧縮成形して樹脂外殻40とする際に、地上子基板10の位置ずれを抑制し、歩留まりの低下を阻止するとともに、地上子1の防水性、防振性の低下を未然に防止する。【解決手段】地上子基板10の少なくとも2か所(例えば矩形状の基板の四隅)から、プレス成形のための上型51、下型52のいずれか一方の型に向かって突出する位置決めピン56を用い、それぞれの位置決めピン56が前記一方の型(好ましくは下型52)に設けられた位置決め孔55に挿入された状態で、プレス成形する。【選択図】図4
