## Abstract

An object is to provide a temperature sensor that requires reduced working manhours to fix the temperature sensor to a temperature measurement object. To achieve the object, the temperature sensor includes: a thermosensitive body; a pair of electric wires electrically connected to the thermosensitive body; a protector made of a resin and covering the thermosensitive body and a part of the pair of electric wires; and a fixing element for a temperature measurement object, which is provided integrally with the protector.

## Claims

### Claim 1

A temperature sensor, comprising:
a thermosensitive body;
a pair of electric wires electrically connected to the thermosensitive body;
a protector made of a resin and covering the thermosensitive body and a part of the pair of electric wires; and
a fixing element provided integrally with the protector and used for fixation to a temperature measurement object.

### Claim 2 (depends on 1)

The temperature sensor according to claim 1, wherein the fixing element is provided in a free region off a sensor element retention area of the protector where the thermosensitive body and the electric wires are provided.

### Claim 3 (depends on 2)

The temperature sensor according to claim 2, wherein the free region has a dimension in a thickness direction set less than a dimension in the thickness direction of the sensor element retention area.

### Claim 4 (depends on 1)

The temperature sensor according to claim 1, wherein the fixing element is a fixing hole penetrating through the protector from a front surface to a rear surface.

### Claim 5 (depends on 4)

The temperature sensor according to claim 4, wherein the temperature sensor is fixed to the temperature measurement object by a fastening tool inserted into the fixing hole.

### Claim 6 (depends on 1)

The temperature sensor according to claim 1, wherein the fixing element is a fixing protrusion protruding from a surface of the protector.

### Claim 7 (depends on 6)

The temperature sensor according to claim 6, wherein the temperature sensor is fixed to the temperature measurement object with the fixing protrusion being inserted into a retention hole provided in the temperature measurement object.

### Claim 8 (depends on 2)

The temperature sensor according to claim 2, wherein the fixing element is a fixing hole penetrating through the protector from a front surface to a rear surface.

### Claim 9 (depends on 3)

The temperature sensor according to claim 3, wherein the fixing element is a fixing hole penetrating through the protector from a front surface to a rear surface.

### Claim 10

The temperature sensor according to 2, wherein the fixing element is a fixing protrusion protruding from a surface of the protector.

### Claim 11

The temperature sensor according to 3, wherein the fixing element is a fixing protrusion protruding from a surface of the protector.

### Claim 12

The temperature sensor according to 4, wherein the fixing element is a fixing protrusion protruding from a surface of the protector.

### Claim 13 (depends on 10)

The temperature sensor according to claim 10, wherein the temperature sensor is fixed to the temperature measurement object with the fixing protrusion being inserted into a retention hole provided in the temperature measurement object.

### Claim 14 (depends on 11)

The temperature sensor according to claim 11, wherein the temperature sensor is fixed to the temperature measurement object with the fixing protrusion being inserted into a retention hole provided in the temperature measurement object.

### Claim 15 (depends on 12)

The temperature sensor according to claim 12, wherein the temperature sensor is fixed to the temperature measurement object with the fixing protrusion being inserted into a retention hole provided in the temperature measurement object.
