In manufacturing of a solar cell module in which a solar cell having a surface electrode to which a tab lead is connected is sealed with a resin, the step of connecting the tab lead and the step of sealing the solar cell with the resin are performed simultaneously at a relatively low temperature that is used for the resin sealing step. To perform these steps simultaneously, the solar cell having the surface electrode to which the tab lead is connected with an adhesive is resin-sealed using a vacuum laminator to manufacture the solar cell module. The vacuum laminator used includes a first chamber and a second chamber partitioned by a flexible sheet. The internal pressures of these chambers can be controlled independently, and a heating stage for heating is provided in the second chamber.

A latent curing agent () of the present invention includes a core member () and a capsule () covering up the surface of the core member (). The core member () includes a secondary particle () and a curing agent () retained in a gap () of the secondary particle (). The curing agent () is liquid at ambient temperature. When the capsule () is destructed so that the curing agent () is emitted into an adhesive, the curing agent () is mixed with other ingredients in the adhesive. A metal alcoholate which is liquid at ambient temperature or a metal chelate which is liquid at ambient temperature is used as the curing agent (), while a silane coupling agent is added to the adhesive. A reaction takes place between the curing agent () and the silane coupling agent to yield cations. By these cations, the epoxy resin undergoes cation in polymerization. Since the cation generating reaction proceeds at a temperature lower than in the case of the conventional adhesive, curing proceeds more promptly and at a lower temperature than in the case of the conventional adhesive.
