Manufacturing method of electronic component unit and electronic component unit

A method for producing an electronic component unit that incorporates an electronic component, the electronic component unit including

• a base member including the electronic component, a pair of terminals connected to the electronic component and extending in a predetermined direction, and an accommodation body configured to accommodate the electronic component by embedding the electronic component therein, to expose each of the pair of terminals to an outside, and having, on an outer face, an engaging portion that protrudes or is recessed in a direction intersecting the predetermined direction, and
• a housing attached to the base member and configured to house the pair of terminals in a manner separated from each other,
• the method comprising:
• a first step of producing the base member;
• and
• a second step of selecting, as the housing, one of a connector-type housing that is integrally and additionally molded with the base member and that has a connector shape with a fitting opening for exposing one ends of the pair of terminals, and a case-type housing that is assembled to engage with the base member and that has a case shape with a pair of accommodation chambers for accommodating the pair of terminals in a manner separated from each other, and assembling the selected housing to the base member, wherein
• in the second step,
• in a case of selecting the connector-type housing, the connector-type housing is integrally and additionally molded with the base member so as to fill the engaging portion of the accommodation body of the base member and so as to expose the one end to the fitting opening, and
• in a case of selecting the case-type housing, a pair of electric wires is connected to the pair of terminals, and then the case-type housing is assembled to the base member so as to engage with the engaging portion of the accommodation body of the base member and so as to accommodate the pair of terminals in the pair of accommodation chambers and insert the pair of electric wires inside and outside the pair of accommodation chambers.
