## Abstract

A terminal connecting structure includes: an electric wire in which a conductor is covered by an insulative covering; a conductor connecting terminal to which a conductor exposed portion in which the covering of an end portion of the electric wire is removed and the conductor is exposed is electrically connected; a water sealant for molding the conductor connecting terminal; and a fixing terminal which includes a terminal fixing portion that is to be fixed and electrically connected to a mount part, and which is electrically connected to a part of the conductor connecting terminal in a state where the water sealant is removed from the part of the conductor connecting terminal.

## Claims

### Claim 1

A terminal connecting structure comprising:
an electric wire in which a conductor is covered by an insulative covering;
a conductor connecting terminal to which a conductor exposed portion in which the covering of an end portion of the electric wire is removed and the conductor is exposed is electrically connected;
a water sealant molded to cover at least the conductor exposed portion in the conductor connecting terminal; and
a fixing terminal which includes a terminal fixing portion that is to be fixed and electrically connected to a mount part, and which is to be fixed to and electrically connected to a part of the conductor connecting terminal in a state where the water sealant is removed from the part of the conductor connecting terminal.

### Claim 2 (depends on 1)

The terminal connecting structure according to claim 1, wherein the terminal connecting structure is to be fixed to the mount part in a state where the terminal fixing portions of a plurality of the fixing terminals are electrically connected to each other.

### Claim 3 (depends on 1)

The terminal connecting structure according to claim 1, wherein the water sealant, covering a fixing-terminal connecting portion of the conductor connecting terminal contacting with the fixing terminal, is configured to be scraped and removed by a fitted connection between the conductor connecting terminal and the fixing terminal.

### Claim 4 (depends on 1)

The terminal connecting structure according to claim 1, wherein the water sealant covering a fixing-terminal connecting portion of the conductor connecting terminal contacting with the fixing terminal, is configured to be melted and removed by a thermal bond between the conductor connecting terminal and the fixing terminal.

### Claim 5 (depends on 1)

The terminal connecting structure according to claim 1, wherein the water sealant, covering a fixing-terminal connecting portion of the conductor connecting terminal contacting with the fixing terminal, is configured to be removed by an ultrasonic bond between the conductor connecting terminal and the fixing terminal.

### Claim 6 (depends on 1)

The terminal connecting structure according to claim 1, wherein the water sealant is molded to and completely encapsulates the conductor connected terminal.

### Claim 7

A terminal connecting method comprising:
exposing a conductor of an end portion of an electric wire in which the conductor is covered by an insulative covering;
electrically connecting a conductor exposed portion of the electric wire in which the conductor is exposed, to a conductor connecting terminal;
molding at least the conductor exposed portion in the conductor connecting terminal, with a water sealant; and
electrically connecting a part of the conductor connecting terminal to a fixing terminal which includes a terminal fixing portion that is to be fixed and electrically connected to a mount part, while removing the water sealant from the part of the conductor connecting terminal.
