Spring member

A spring member that presses a first pressed body and a second pressed body, which face each other in a first direction, in directions away from each other in the first direction, the second pressed body having a heat-generating body, the spring member comprising:

• a first member;
• and
• a second member,
• wherein the first member is formed of a material having a higher thermal conductivity than a material forming the second member,
• the first member includes first abutting portions which are formed at both end portions thereof in a second direction orthogonal to the first direction and abut on one pressed body of the first pressed body and the second pressed body, and a second abutting portion which is formed at an intermediate portion thereof in the second direction and abuts on the other pressed body of the first pressed body and the second pressed body,
• both end portions of the second member in the second direction press the one pressed body via the first abutting portions, and an intermediate portion of the second member in the second direction presses the other pressed pressing body via the second abutting portion, and
• a protective protrusion to which heat from the heat-generating body is transferred is provided to the first member, the protective protrusion being formed integrally with the first member.
