## Abstract

The present invention provides a connection structure and a manufacturing method therefor capable of increasing reliability of a connection part compared to the prior arts. A connection structure according to the present invention includes a plurality of conductive members, a connection part that electrically connects the conductive members, and an electrically insulating molded body in which the connection part is embedded. It is thereby possible to physically reinforce the connection part of the conductive members, keep the connection part in a hermetically sealed condition, thereby prevent corrosion and increase reliability compared to the prior arts.
