A heat exchanger includes a pipe made of aluminum, a thermistor, and an attaching portion with which the thermistor is attached to the pipe. The pipe carries a flow of refrigerant. The thermistor detects a temperature of the refrigerant. The pipe includes a sacrificial layer provided on a part of a surface of the pipe. The sacrificial layer is lower in potential than the aluminum of the pipe. The attaching portion is higher in potential than the sacrificial layer. At least one part of the attaching portion is attached to the surface of the pipe where the sacrificial layer is not provided. The attaching portion includes a brazed portion that is higher in potential than the sacrificial layer. The thermistor is attached to the pipe with the brazed portion.

A wiring component with physical quantity sensor is provided with an electric wire, a physical quantity sensor to detect a physical quantity of the electric wire, a holding member that is composed of a molded body covering a portion in a longitudinal direction of the electric wire and has a holding hole to house the physical quantity sensor, and an attachment member attached to the holding member. The physical quantity sensor is prevented from coming out of the holding hole by the attachment member.

The invention relates to an apparatus (1) for simpler sensing the temperature in roasting of coffee. The apparatus (1) is provided for roasting coffee beans and comprises: a chamber (10) in which coffee beans can be received for roasting, and a device (80) for roasting the coffee beans received in the chamber (10). The chamber (10) is delimited by at least a bottom (11) and a sidewall (12) extending from the bottom (11), wherein the sidewall (12) comprises an outer side (121) oriented to face away from the chamber (10), and wherein a temperature sensor (90) is provided at the outer side (121) of the sidewall (12) for sensing a temperature inside of the chamber (10).
