PROBLEM TO BE SOLVED: To provide an electronic device capable of suppressing the position deviation and inclination of an electronic circuit part by a resin injection pressure and securing a waterproof property without adding a new process, and to provide a molding die therefor. SOLUTION: An acceleration sensor unit comprises an electronic circuit part, a case and a connector housing, and the case and the connector housing are molded by a cavity 24 for the case and a cavity 25 for the housing. After a melted resin 3 is injected to the molding die 2 until it is cooled and solidified, the electronic circuit part 10 is held in holding parts 220a-220d. Thus, the position deviation or the like by the resin injection pressure is suppressed. After it is cooled and solidified, when the acceleration sensor unit is taken out, a hole part is formed by the holding parts 220a-220d. However, the opening of the hole part is surrounded by the connector housing. Thus, the waterproof property is secured without adding the new process of sealing the hole part.
