COMPOSITE MOLDING, MANUFACTURING METHOD THEREOF, PRESSURE SENSOR, AND MANUFACTURING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a composite molding of a configuration in which the airtightness of surface boundary between a primary molding and resin is hardly impaired, a manufacturing method thereof, a pressure sensor, and a manufacturing method thereof.SOLUTION: A connector case 3 of a pressure sensor 1 is made of resin containing reinforced fiber 3a extending in the longitudinal direction, and has a first portion 31a and a second portion 31b extending in a first direction D1. In the pressure sensor 1, the reinforced fiber 3a within an area from a first surface boundary 2a to the first portion 31a is oriented so that the longitudinal direction faces the first direction D1, as compared with the reinforced fiber 3a within the second portion 31b. Therefore, even when the temperature of the connector case 3 declines, a portion near the first surface boundary 2a is hardly shrunk in the first direction D1, and the airtightness of surface boundary between a mold IC 2 and the connector case 3 is hardly impaired. 【課題】第１次成形体と樹脂との界面の密着性が損なわれ難い構成の複合成形体およびその製造方法、圧力センサおよびその製造方法を提供する。【解決手段】圧力センサ１は、コネクタケース３が、長手方向に延在する強化繊維３ａを含有する樹脂で構成されており、第１方向Ｄ１に延在する第１部分３１ａと第２部分３１ｂを有する。圧力センサ１では、第１界面２ａから第１部分３１ａまでの領域内の強化繊維３ａが、第２部分３１ｂ内の強化繊維３ａに比べて、長手方向が第１方向Ｄ１を向くように配向している。このため、コネクタケース３の温度が低下した場合でも、第１界面２ａ付近の部分が第１方向Ｄ１に収縮し難くなり、モールドＩＣ２とコネクタケース３との界面の密着性が損なわれ難い。【選択図】図１
