摘要:
Opposed to a substrate (2) having a functional element (1) with a functional portion (1a) mounted thereon, there is disposed a resin sealing plate (3) provided with an opening (3a) corresponding to the functional portion (1a) of the functional element (1) with a given spacing therebetween. Impregnation and filling of a sealing resin (5) in the spacing between the substrate (2) and the resin sealing plate (3) are carried out by the use of the capillary phenomenon. Thus, resin sealing of the functional element (1) can be realized without damaging to the function of the functional portion (1a).

The present disclosure provides an optical functional device-mounted module which needs no expensive or special members, can be reduced in size, and provide a producing process thereof. A bank to dam a liquid sealing resin is provided on a substrate around an optical functional device, the substrate being formed with a predetermined wiring pattern and having the optical functional device mounted thereon. The liquid sealing resin is filled between the functional device and the bank by dropping the liquid sealing resin therebetween. A package component member having a light transmission hole corresponding to an optical function part of the optical functional device is brought into contact with the bank such that the light transmission hole is opposed to the function part of the optical functional device, thereby causing the package component member to contact with the liquid sealing resin. The package component member is fixed onto the substrate by curing the liquid sealing resin and the bank is finally cut off and removed.

A protective circuit capable of coping with broad voltage variations of a battery unit to interrupt its charging/discharging current path as damages to the heating unit are prevented from occurrence is disclosed. The protective circuit includes fuses, connected to a charging/discharging current path in series between a battery unit and a charging/discharging control circuit, and a heating unit composed by a series connection of resistors. One of two ends of the resistor which is not connected to the peer resistor is connected to a current path of the fuses. The ends of the resistors not connected to the fuses, are provided with a plurality of terminals selected for connection to a current control element that controls the current flowing through the heating unit, as a range of voltage variations of the battery unit is taken into account.
